What is It Directions: Answer the following questions. Write your answer on your activity notebook. 1. What are the different types of asexual reproduction? 2. Explain in words or illustration the sexual reproduction of animals. Plant Reproduction versus Animal Reproduction Reproduction Plants, animals, and other organism have the ability to reproduce. Reproduction is a biological process in which different organisms have the ability to produce another of their kind. With this ability, organisms are able to improve their species and enhance their physical characteristics, because only those that have the genes necessary for survival can proliferate and pass them on to the next generation. In plants and animals, reproduction may either be sexual or asexual. Asexual Reproduction Asexual reproduction does not involve gametes or sex cells. This type of reproduction can be observed in some plants and in lower forms of animals. 4 Types of Asexual Reproduction 1. Budding- an organism is reproduced by forming an outgrowth, or a “bud”, from a part of the parent organism’s body. Example is Hydra. Figure 1. Hydra 2. Fragmentation- an organism is produced from the detached body part of its parent. Example is some species of sea stars. Figure 2. Sea stars 3. Binary fission- a parent organism (e.g., a unicellular organism) splits into two “daughter” organisms. This type of asexual reproduction is usually done by prokaryotic organisms (e.g., bacteria) and some invertebrates. Example is Cyanobacteria. Figure 3. Cyanobacteria 4. Vegetative reproduction- a plant part is used to reproduce another plant. Example is strawberry and kamote, etc.. Figure 4. Plants 5 5. Spore formation- this involves the production of spores, which are specialized asexual reproductive cells. Example is ferns. Figure 5. Fern Sexual Reproduction On the other hand, sexual reproduction involves the union of gametes (i.e., the sperm and the egg cell) inside or outside the body of an organism. This type of reproduction is exhibited only by higher forms of organisms, including humans. In this process, the sperm and the egg fuse to create a fertilized egg known as the zygote, which will eventually become the embryo. Figure 6.1 shows the process necessary for sexual reproduction to occur. Figure 6.1.Sexual reproduction in humans. Reproductive Traits in Organisms The reproduction of different organisms plays a vital role in the continuation of their species, as well as their survival. There are a lot of physical differences in the reproductive systems of plants and animals, but they also share certain similarities. Plants and animals both use color display for reproduction. Plants use their physical characteristics to attract pollinators. Some plants have bright-colored flowers to attract insects, and thus enabling the transfer of pollen from one flower to another. Figure 6.2 shows a bee feeding on nectar from a dandelion. As the bee feeds itself, the pollen grains get attached to its hairy body. When the bee sips nectar from another flower, the pollen grains that previously got attached to it are then transferred; thus, reproduction happens. 6 Figure 6.2. Pollination of dandelion by a bee Some animals also use color display to attract a mate. The peacock in figure 6.3 shows a magnificent color display of its feathers during courtship. The peacock does this to attract the female peafowl, the peahen. Figure 6.3. A peacock displaying his plumage to a peafowl. One distinguishing characteristic of animals is sexual selection, wherein some male species compete with other males to copulate with females. This form of natural selection allows successful transfer of genes from one generation to the next. Another difference between plants and animals is their method of fertilization. Sexual reproduction in most animals requires physical interaction with each other in close proximity. In comparison, plants need a vector, such as an insect or a bird. Thus, animals and plants have different ways of reproduction, but their main goal is the same: to extend their species. 7 What’s More Directions: Column A is the definition of term in the Column B.

What is the similarity and difference in terms of their reproduction? Let’s connect to the next topic but before that try to rearrange 13 the rumbled letters to give you a clue on the lesson to be discussed. The rumbled letters are M V E P N E L D E O T . How do Plants and Animals differ? What’s New Directions: Complete the following table to show the differences in the development of plants and animals. Write your answer on your activity notebook. Feature Plant Animal Life cycle Growth pattern Cell growth (in size or in number) Change in body shape Formation of gametes What is It Directions: Answer the following problems. Write your answer on your activity notebook. 1. What are the differences of plants and animals development? 2. Illustrate the comparison of life cycles between plants and animals. Developmental Difference of Plants and Animals Development Plants and animals have progressed differently. Based on phylogenetic evidence or the evolutionary history of organisms, the primitive ancestor of plants and animals was likely a unicellular eukaryote. However, based on molecular evidence from gene comparisons, there is not much similarity between the genes that make up the body plan of plants and of animals. At the unicellular stages of their development, plant cells are positionally fixed, which means that they are not capable of movement, whereas animal cells are motile or capable of movement. During the growth stages, the body plan of plants is highly regulated by the environment because plants cannot choose or change their growing locations, whereas the body plan of animals is clearly determined by its genes. Plant and animal life cycles are also different from one another. Most plants undergo alternation of generations, where they have sexual and asexual life cycles, whereas the animal life cycle has only one continuous multicellular stage (after fertilization). Figure 6.4 shows the comparison between the life cycles of plants and animals. 14 Figure 6.4. Comparison between life cycles of animals and plants The processes in the formation of gametes are also different between plants and animals. During meiosis, plants produce spores first before forming the gametes, whereas in animals, the gametes are directly formed. Another developmental difference between plants and animals is shown in their morphogenesis, or change in shape. Plants develop by going through a longer period of morphogenesis than animals. Plants just grow and develop continuously until they die, whereas animals develop into a distinct and complete body shape (usually during adulthood). Plants grow by increasing their cell size, whereas animals grow by increasing the number of their cells. What’s More Directions: Column A is the definition of term in the Column B.
