I’m a Survivor: Structures and Functions of Animal and Plant Survival TEKS Targeted: 3.10 A ELPS Targeted: Overview: This activity is designed to give students the opportunity to explore specific structures and functions in a variety of both plants and animals. It is important that students are able to identify how these structures and functions help the organism survive in its particular environment. This activity allows students to examine plants and animals they are probably not too familiar. In this lesson, students will also work on their observation and critical thinking skills. Grade Level: 3 Duration: Plant activity – 45 minutes to 1 hour; Brainium – 45 minutes to 1 hour; Journal activity – 20 minutes. Materials: Plant cards (1 set of cards for every 8 students) Animal Brainium Game Cards Time lapse video of bell pepper plant at http://www.naturefootage.com/video_clips/BF41_084 Instructions: Engage Activity 1. Each student is given an observation table. These tables should be glued in their journals. 2. Tell students they are going to watch a video and their job is to make observations about what they see in the video. These observations should be recorded on the first line of there observation table. 3. The teacher should pause the video at the beginning and allow students to make/record their observations. 4. Once the students are ready, play the entire video and have them make/record observations again. 5. The teacher leads a discussion about the structures and functions they observed and how those structures and functions help the plant survive and/or make more plants. Plant Activity 1. Students should be paired up with another student. 2. The plant cards will be rotated from group to group so each student should start out with 3 to 4 cards from the set. 3. Students will make observations about the plant’s structures and functions shown in the picture. They should also read the information on the back of the card (Things you can’t see in the picture…). The pair of students discusses their observations. 4. Each student should then record the observations that were discussed in the first column of the table in their journal. 5. The teacher then asks the students to discuss and explain why they think those structures and functions help the plant survive in its environment. 6. The explanation should be recorded in the table. 7. Cards will be passed from pair to pair until each group has completed all 12 plants. © Marianne Dobrovolny – Region 17 Education Service Center Graphics are from various online resources and are intended for educational purposes only. Page 1 Animal Adaptation Brainium 1. In this game of Brainium, students will be acting, drawing, sculpting and identifying animals and their beneficial structures and/or function. 2. Students are put in teams of 3 or 4. 3. Two teams will play together and should move to a similar area. Game rules: Each card has a specific color, the name of an animal, and a few examples of structures/functions and how those help it survive. The object of the game is to get your team members to guess the animal on your card by acting it out (yellow cards), drawing it (green cards), or sculpting it (red cards). The blue cards are trivia cards and have 2 or 3 characteristics of an animal. These are read out loud to the team. The team then tries to identify the animal those characteristic are describing. Setting up: o Without looking at the card, students will set them up in four separate stacks. o The dice is rolled by each student and the person with the highest number will go first for their team. Time limits (one person from each team will be a designated timer): o All blue cards have a 30 second time limit from the time the person finishes reading the card. o All yellow and green cards have a 90 second time limit from the time the person begins acting or drawing. o Red cards have the time limit identified on the card. Scoring (one person on each team should be a designated score keeper): o The first student will roll the dice. The number will determine which set of cards the player draws from as follows: 1 = Yellow, 2 = Green, 3 = Red, 4 = Blue, 5 – Loose a turn, 6 = Players choose. o To get a point the team must guess the correct animal. Once they have guessed the animal, they must ALSO give one special structure or function it has and tell how that structure of function helps it survive. IMPORTANT NOTE: Not all possible answers are typed on the cards so students should check with the teacher if they are not sure if the answer given is correct. o 1 point is given for each correct guess. o If a team cannot correctly guess the animal, a structure/function and how it helps it survive within the time limits, then the other team has a chance to steal the point. The team with the highest score at the end of the game wins. Journal Ideas: • Have students write about 2 or 3 plants and/or animals that they learned about. You can give them the following paragraph stem to help them get started. • “Today I learned about a ___________. I learned that it…..” • You may want to have the students pick at least 1 or 2 plants/animals that they had never heard of or are not familiar with. © Marianne Dobrovolny – Region 17 Education Service Center Graphics are from various online resources and are intended for educational purposes only.

Page 8 Key: (the information in the sections below was compiled using various web pages). Blue heavenly morning glory is a robust herbaceous perennial. Because of its aggressive climbing habit it is able to twine around other trees and shrubs out-competing them for sunlight. It can also spread into natural areas choking out and mothering native plants. The deep root system extends in many directions allowing the plant to spread and establish in new areas competing with other plants for nutrients and water. Once established, it is very difficult to eradicate the plant. Vegetative fragments of the plant, including shoots and roots, are often dumped with garden wastes, thus spreading the plant further. The climbing capability along with its reproduction and spreading habits can seriously hinder the growth process of host plants, and decrease biodiversity in the surrounding environment. The dense covering of plant hairs performs a vital function for the plant in the form of water conservation. In the dry environment in which it lives, panda plants must conserve what little water it can absorb from the soil. The dense mat of hairs growing from the leaf slows the movement of air directly across the leaf surface, thereby reducing water vapor loss (transpiration). The “deadair” space created by the numerous hairs insulates the leaf from its harsh external environment, too. In addition, the white-silver appearance of the leaves reflects light, lessening the chances of the leaves overheating. Plants grow far away from each other. The plants that survive in the desert compete for the small amount of water available, and so they cannot grow close together. Aloe has deep roots that are very efficient at absorbing a lot of water in a short amount of time (The desert has short, intense rain storms). The fat, fleshy, spongy leaves absorb water quickly and hold water longer. Plants with these fat-leaves are called succulent. Thorns on the edge of the plant keep animals from eating the plant to get to the water stored inside. The leaves are waxy (like a candle) to keep water inside. The wax layer acts like plastic wrapper. The leaves are shiny and smooth to reflect the sun light away from the plant and keep the plant cooler. The plant self-shades. This means that the top leaves are larger and create shade for the tender young leaves growing underneath. Some aloes have leaves that fold in during the hot summer months. This helps to protect the softer and younger leaves from extreme temperatures. Leaves open again in cool weather. The flower of the aloe attracts birds and insects that pollinate the plant. The aloe produces many winged seeds that are easily spread far and wide by the wind. With a few exceptions, cacti are succulent plants and, like other succulents, they have a variety of adaptations that enable them to survive in hot and dry environments. In most species of cacti the leaves have evolved into spines which not only defend the cactus against herbivores but also provide shade that lowers the plants water loss through transpiration. The spines grow from specialized structures called areoles, homologous to the nodes on other plants. Enlarged stems carry out photosynthesis and store water. Unlike other succulents, the stem is the only part of many cacti where this takes place. Cacti often have a waxy coating on their stems to prevent water loss and potentially repel water from their stems. Because of the plants' high water-retention ability, detached parts of the plant can survive for long periods and then grow new roots from anywhere on the plant body when rain comes. The bodies of many cacti have become thickened during the course of evolution, and form water-retentive tissue that is in the optimal shape of a © Marianne Dobrovolny – Region 17 Education Service Center Graphics are from various online resources and are intended for educational purposes only. Page 9 Mesquite has an extremely long root system to draw water from deep underground near the water table. The tap root of the Mesquite can reach 40 to 80 feet under the ground. Plants grow far away from each other. The plants that survive in the desert compete for the small amount of water available, and so they cannot grow close together. Sharp, long, strong thorns keep animals from eating the plant. These thorns are so strong, they can go through sneakers. sphere or cylinder (combining highest possible volume with lowest possible surface area). By reducing its surface area, the body of the plant is also protected against excessive sunlight. The plant body itself is also capable of absorbing moisture (through the epidermis and the thorns), which is especially important for plants that receive most of their moisture in the form of fog. Most cacti have a short growing season and long dormancy. This is helped by the ability to form new roots quickly. Two hours after rain following a relatively long drought, root formation begins in response to the moisture. Apart from a few exceptions, an extensively ramified root system is formed, which spreads out beneath the surface. Cacti often have very shallow roots that spread out widely close to the surface to collect water, an adaptation to infrequent rains. The leaves are small to conserve moisture. A magnificent example of adaptation to weedy life in perennial grassland is provided by the common dandelion, Taraxacum officinale. In addition to its deep taproot and rosette of leaves, which help it to deal with competition of the grasses, it has remarkable powers of regeneration from any part of the rootstock which may be severed. The flat rosette of leaves avoids the blade of a mowing machine and it is not easy for a grazing animal to consume them, while the more exposed flowering scape is richly provided with unpalatable latex. The inflorescence buds are produced very near the ground level and develop rather slowly in this position (from which they will not be cut even by a very fine-set lawn mower). Suddenly the scape elongates and flowering and fruit-setting takes place rapidly (assisted by precocious development of the apomictically-produced embryos). All of these features are characteristic of the genus Taraxacum as a whole and must be looked upon as preadaptations to weediness. Switchgrass is a hardy, deep-rooted, perennial rhizomatous grass that begins growth in late spring. It can grow up to 2.7 m high, but is typically shorter than big bluestem grass or indiangrass. The leaves are 30-90 cm long, with a prominent midrib. Switchgrass uses C4 carbon fixation, giving it an advantage in conditions of drought and high temperature. Its flowers have a well-developed panicle, often up to 60 cm long, and it bears a good crop of seeds. The seeds are 3-6 mm long and up to 1.5 mm wide, and are developed from a single-flowered spikelet. Both glumes are present and well developed. When ripe, the seeds sometimes take on a pink or dull-purple tinge, and turn golden brown with the foliage of the plant in the fall. Switchgrass is both a perennial and self-seeding crop, which means farmers do not have to plant and reseed after annual harvesting. Once established, a switchgrass stand can survive for ten years or longer. Unlike corn, switchgrass can grow on marginal lands and requires relatively modest levels of chemical fertilizers. Overall, it is considered a resourceefficient, low-input crop for producing bioenergy from farmland. The scientific name of this organism is Victoria amazonica. The common name for this organism is Giant Water Lily. General Description Victoria amazonica is in the Plantae kingdom. The flower itself is white and only blooms at night. The colour of the lily changes however when it is pollinated to a pinky purple. When the lily is still white in colour and needs to be pollinated it gives off a butterscotch and pineapple scent that attracts the beetles that pollinate the flower; another way the flower attracts beetles is its power to heat up the core of the flower. If the heat outside is 85°C then inside the flower can be up to 95°C! The flower is approximately the size of a soccer ball and only lives for three days. The most interesting thing about this flower is the large leaves that it creates. The leaves can grow up to 46 centimeters in size and can hold up to 136 kilograms, the leaves are flat Boston Ivy the plant secretes a sticky calcium carbonate,[1] which serves as an adhesive pad and gives it the ability to attach itself to a wall without requiring any additional support. While it does not penetrate the building surface but merely attaches to it, nevertheless damage can occur from attempting to rip the plant from the wall. However, if the plant is killed first, such as by severing the vine from the root, the adhesive pads will eventually deteriorate to the point where the plant can be easily removed without causing any damage to the wall. © Marianne Dobrovolny – Region 17 Education Service Center Graphics are from various online resources and are intended for educational purposes only. Page 10 before growing rims at the edge of the leaf. The leaves are strong and stiff thanks to the strong bottom of the leaves. The bottoms are covered with spines to help support the ribs. The bottom of the leaf is maroon in colour. The Giant Water Lily does not grow year round in areas where it is not a native species, such as Great Britain; it only grows and reproduces in the summertime when the climate is warm. However, in its native Brazil and in the Amazon it grows all year long, due to the optimum conditions. Specific Adaptations to the Environment The Giant Water Lily adapts to the environment by growing thorns on the bottom of the leaves to protect itself from fishes and other predator that might want to eat it. Another adaptation is the rim around the edges of the leaves. These rims help protect the leaf from birds and insects that might want to eat the leaves (the rim is a barrier between the insects and the leaf). The third adaptation of this Giant Water Lily is that the flower only lives for three days, it traps the beetles that come to pollinate the flower inside its core and then releases all its pollen on these beetles. This enlarges the percentage of pollen that gets transported to other flowers for pollination. The venus flytrap (Dionaea muscipula) is a carnivorous plant that catches and digests animal prey consisting mostly of insects and arachnids. The trapping structure is formed by the terminal portion of each of the plant's leaves. The edges of a venus flytrap leaf are equipped with teeth-like protrusions called cilia, while the inside has red pigmentation that attracts insects. The venus flytrap reveals the remarkable diversity in nature—a carnivorous plant containing several traps that can snap shut in milliseconds to capture prey. The venus flytrap is found in nitrogen-poor environments, such as bogs. The nutritional poverty of the soil is a reason for the plant to have such elaborate traps as an adaptation: insect prey provide the nitrogen for protein formation that the soil cannot. The venus flytrap is a small herb, forming a rosette of four to seven leaves, which arise from a short subterranean stem that is actually a bulb-like rhizome. Longer leaves with robust traps are generally formed after flowering. Flytraps that appear to have more leaves are generally colonies, formed by rosettes that have divided beneath the ground. Each leaf blade is divided into two regions: a flat, heart shaped photosynthesis-capable petiole, and a pair of terminal lobes hinged at the midrib, forming the trap, which is actually the true leaf. Venus flytraps produce white flowers in the spring. The seeds are small, shiny, and black. Trapping and digestion mechanism The terminal lobes, hinged at the midrib, exhibit rapid plant movements, snapping shut when stimulated by prey. The trapping mechanism is tripped when prey items stumble against one of the three hair-like trichomes that are found on the upper surface of each of the lobes. The trigger hairs must be touched twice in quick succession, preventing non- Potatoes contain toxic compounds known as glycoalkaloids, of which the most prevalent are solanine and chaconine. Solanine is also found in other plants in the family Solanaceae, which includes such plants as the deadly nightshade (Atropa belladonna), henbane (Hyoscyamus niger) and tobacco (Nicotiana) as well as the potato, eggplant, and tomato. This toxin affects the nervous system, causing weakness and confusion. These compounds, which protect the plant from its predators, are, in general, concentrated in its leaves, stems, sprouts, and fruits.[61] Exposure to light, physical damage, and age increase glycoalkaloid content within the tuber;[62] the highest concentrations occur just underneath the skin. Cooking at high temperatures (over 170 °C or 340 °F) partly destroys these. The concentration of glycoalkaloid in wild potatoes suffices to produce toxic effects in humans. Glycoalkaloids may cause headaches, diarrhea, cramps, and in severe cases coma and death; however, poisoning from potatoes occurs very rarely. © Marianne Dobrovolny – Region 17 Education Service Center Graphics are from various online resources and are intended for educational purposes only. Page 11 prey stimuli such as raindrops from triggering the trap, whereupon the lobes snap shut in around 100 milliseconds. The edges of the lobes are fringed by stiff hair-like protrusions or cilia, which mesh together and prevent large prey items from escaping. These protrusions, and the trigger hairs, are probably homologous with the tentacles found in this plant’s close relatives, the sundews. The holes in the meshwork allow small prey to escape, presumably because the benefit that would be obtained from them would be less than the cost of digesting them. If the prey is too small and escapes, the trap will reopen within 12 hours. If the prey moves around in the trap, it tightens and digestion begins more quickly. The speed of closing can vary depending on the amount of humidity, light, size of prey, and general growing conditions. The speed with which traps close can be used as an indicator of a plant's general health. Venus flytraps are not as humidity dependent as are some other carnivorous plants, such as Nepenthes, Cephalotus, most Heliamphora, and some Drosera. The venus flytrap is one of a very small group of plants that are capable of rapid movement, such as Mimosa, the telegraph plant, sundews, and bladderworts. The mechanism by which the trap snaps shut involves a complex interaction between elasticity, turgor, and growth. In the open, untripped state, the lobes are convex, but in the closed state, the lobes are concave, forming a cavity. It is the rapid flipping of this state that closes the trap, but the mechanism by which this occurs is still poorly understood (Forterre et al. 2005). Digestion is catalyzed by enzymes secreted by glands in the lobes. Digestion takes about ten days, after which the prey is reduced to a husk of chitin. The trap then reopens, and is ready for reuse—even though the trap rarely catches more than three insects in its lifetime. The fruit serves as a mother's womb where the embryo of a baby plant is nurtured. It protects the embryo, or the seed, in almost the same way as the mother protects her small ones. The flesh of the fruit serves as a protective lining as the seed develops. And, before the seed is ready to be sowed, the fruit is unripe and tastes sour. The sourness of the fruit discourages us from eating it. Imagine what would have happened if raw fruits were sweet. It would have had an underdeveloped seed. After eating the fruit, you would throw the seed away. But, the seed, like a premature baby, would not have been able to bring about the birth of a new plant. So, nature decided that fruits should become sweet only when they are ripe and the seeds ready to be sown on earth. The ripe fruit tempts you to eat it. So that after you eat it and throw the seed on the ground, it germinates in the soil to bring about a new plant. Isn't that smart? © Marianne Dobrovolny – Region 17 Education Service Center Graphics are from various online resources and are intended for educational purposes only.
