Procedures: Teacher’s Activity Pupil’s Activity A. Preparatory Activities 1. Prayer Please let us all stand and let us pray. (children are praying) 2. Greetings Good morning children, How are you Good morning teacher, we are today? I’m fine too. fine thank you, How about you? 3. Checking of attendance now as I call your name please raise your Yes, teacher! right hand and shout ‘darna’, so that teacher would know that you’re present today. Understood? 4. Review What was our topic yesterday class? Our topic yesterday was all Who can answer? about the human reproductive Very good! system. What are the two types of human The two types of human reproductive system? What are they? reproductive system are the Excellent answer! male reproductive system and the female reproductive system. 5. Engagement (Motivation) Alright children let’s have some fun this (children are raising their hands morning, who wants to play? because they’re excited to have Okay now lets play so please listen fun) carefully to teacher as I explain the rules of the game. (group the children into 3 groups, give (Children are busy trying to and explain the direction) arrange the letters to get the correct word). Activity: “Fix Me”(jumbled letters) Direction: arrange the letters to get the correct word. 1.FERTILIZATION 2. INTERNAL 3.BUDDING 4. PARTHENOGENESIS 5. FRAGMENTATION before we start the game here is the rubrics for this activity. RUBRICS CRITERIA 10 Cooperation Organization Time Frame Presentation TOTAL 8 6 5 did you understand children? I’ll give you 3minutes to do this activity, you may start now. Very good all groups got the correct answers! Let us clap our hands! (the teacher will have a short talks about those words they encountered awhile ago. Let the pupils (yes teacher) review how to spell the words correctly and give its meaning) B. Developmental Activities 1. Presentation (presentation of the lesson) Now what do you think about the words that you assembled earlier? Where do we often find or use this words? Example the word fragmentation, who can give me a short idea of the word fragmentation? What is fragmentation? Ans. Fragmentation is another form of asexual reproduction of a plants. How about parthenogenesis? Is an embryo that develops from unfertilized cell. It is a method in which a new individual developed without fertilization example are ants, wasps and bees. Base on your activity class who has an idea of what is our topic this morning ? Who can answer? Okay kim go ahead. Okay very good kim , lets have a lets go clap for kim! Kim is raising her hand) teacher I think our topic for this morning is about the reproductive structure of animals and plants a. Setting of standards (class rules, scoring rubrics) Before we proceed with our topic this morning let me present to you the classroom rules and regulations. Is it okay with you class? In this classroom I only want you children to BE SMART SAY PLEASE AND THANKYOU MAKE FRIENDS AND BE THOUGHTFUL ARRIVE ON TIME, PREPARED, AND READY TO LEARN RESPECT YOURSELF AND OTHERS TRY YOUR BEST! Is it okay class? 2. Explanation: (Discussion of the concept or the lesson) Yes teacher! ASEXUAL AND SEXUAL REPRODUCTION IN PLANTS HOW DO PLANTS REPRODUCE SEXUALLY? Through the process of fertilization when male and female gametes combine to produce offspring. Flowering plants reproduce sexually through a process called pollination. ASEXUAL REPRODUCTION Only requires DNA from one parent. It creates offspring that are genetically identical to the parent(clones) Clones lack genetic diversity. This makes them more susceptible to disease. It also makes them less adaptable to changes in the environment. Runners- stolon/stem grows horizontally above the ground. The buds are formed at the nodes of runners. Ex. Strawberry, Bermuda grass. Tubers- these underground growth produce new plants from stems or growing points called eyes. Ex. Potato, sweet potato, Bulbs- are shortened underground storage structures. They are stems they are stems that are enclosed with fleshy, concentric layered leaves. Ex. Garlic, onion. Rhizomes- these stems grow sideways along with the soil or just below the surface. They branch apart to produce new points of growth. Ex. Ginger plants. Fragmentation Is another form of asexual reproduction. It involves new plants growing from small parts of the parent plant that fall to the ground. For example, animals or the wind can break stem or leaves off plants. This is one of the ways thar plants like to liverworts and mosses reproduce. ALTERATION OF GENERATIONS Fertilization: Nonvascular plants- need a film of water for the sperm to reach the egg. Vascular plants- do not need water for the sperm to reach the egg. MODIFICATIONS IN FLOWERS Complete Flowers- have all four organs (sepals, stamens, and pistils) Ex. Morning glory and lily. Incomplete Flowers- lacks one or more of the four organs Ex. Squash and corn. Example of complete flower Example of incomplete flower SEXUAL AND ASEXUAL REPRODUCTION IN ANIMAL Sexual reproduction is the production of a new organisms from two parents by making use of their sex cells or gametes. Humans, fish, frogs, cats, and dogs, all reproduce by the method of sexual reproduction. HOW DOES FERTILIZATION TAKE PLACE? When a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, zygote is formed. From there, the zygote will move down the fallopian tube into uterus. The zygote then burrows into uterus lining. The stage of development between zygote or fertilized egg and the newly formed baby is called embryo. ASEXUAL REPRODUCTION Following are the important features of asexual reproduction. No formation of gametes fertilization takes place. Only one parent is involved. The process occurs in very less time. The offspring produce are exact copies of the parent, there is no variation. The growth of the offspring is rapid. 3. Elaboration: (an activity to deepen their understanding about the lesson) Now to test your understanding in our lesson today lets have a short activity. Are you ready class? Answer it by group. I will give you 5 minutes to do Yes teacher! this activity. Understood? LET’S CHECK! 1. What are the female parts of a flower? 2. What is alteration of generation? 3. Differentiate internal and external fertilization. 4. Cite examples of animals that produce asexually. 5. Enumerate the type of asexual reproduction. C. Concluding Activities 1. Generalization: ( 2. Application: (An activity applying their learning about the lesson) Direction: compare and contrast reproductive structure of animals and plants. 3. Valuing: (Let the pupils value importance of the lesson) 1. Why is reproduction important? the 2. Does reproduction also important to us? How? 1. Reproduction is important to produce offspring in order for a species to continue they must be able to produce viable offspring. 2. Yes teacher, because it can affect in our daily 3. How important plants and animals in our lives? What will happen to us if there is no plants, vegetables and fruits? Can we survive ? living if there is no reproduction happen. Our food supply will be in jeopardy without sound animal reproductive practices. 3. No teacher. 4. How about if there is no meats and fish can we survive for a long time? 5. What will happen to our body ? Yes because if there is no meat, vegetables and fruits our body will become weaker and weaker because our body needs nutrients vitamins and minerals to survive and we can only get it from the plants and animals, so it is very important to take care of our surroundings , the plants in there, the animals because without them we will not able to live . our body need protein, vitamins, minerals and that comes from different kind of meat, vegies and fruits. So we must take care of them and know its value and how important it is in our lives. Yes teacher! IV. Evaluation: (assessment either traditional or authentic assessment) Multiple Choice. Choose the letter of the correct answer. 1. Sexual Reproduction requires ______parts of the plant. a. Only male b. Only female c. Male and female d. Small parts of plants 2. Which of the following is the male part of the plant? Provide possible answers of the pupils a. Pistil b. Stamen c. Stigma d. Style 3. Simple animals, such as HYDRA and sponge, reproduce asexually by_______. a. Budding b. External fertilization c. Internal fertilization d. Regeneration 4.

The production of new plants from underground stem is an example of _____ reproduction. a. Asexual b. Binary fission c. Budding d. Sexual V. Assignment: (optional) Direction: in a short bond paper draw an animal or plants that you think it represent your character.
