- 29. • The classroomhas five learning areas. Each of them offers a different topic that you will observe and examine. Write your notes as you go on. • I will assign each group to a designated learning area. After 3 minutes, you will proceed to the next learning area until you finish visiting all learning areas.
- 30. Before we dothat, let us recall the guidelines in doing an activity. • Be cooperative and respectful. • Cooperate with your groupmates. • Don’t disturb other groups. • Follow directions correctly.
- 31. • (Designated learningareas for the groups:) • Group 1 – Area 1 • Group 2 – Area 2 • Group 2 – Area 3 • Group 4 – Area 4 • Group 5 – Area 5
- 32. Learning Area 1:Vegetative Reproduction “Can You Grow Plants from ‘Eyes’?” 1. In this activity, a potato tuber was cut into pieces and was planted. 2. Observe and examine the changes in the tubers. 3. Where did the new plants come from? 4. How many parents did it need to reproduce new plants? 5. What plants reproduce in the same manner? Cite some examples.
- 33. Learning Area 2:Pollination “Can You Grow Plants from ‘Dust’?” 1. Study the male and female parts of the flower. What qualities do they have? 2. What does the stamen have? What do we call the dust-like particles in it? 3. Touch the pistil. What does it feel like? Why do you think it is sticky? 4. What process spreads pollen to other plants? What organisms aid in this process? 5. How many parents are needed to reproduce?
- 34. Learning Area 3:Budding “Can One Become Two?” 1. Look at this hydra, examine how the hydra develop. 2. What have you noticed growing from the parent hydra? 3. How many parents are needed to reproduce a new organism of this kind?
- 35. Learning Area 4:Internal Fertilization “Sperm and Egg Cells” 1. Study the picture. Where does a sperm cell come from? Where does an egg cell come from? 2. How many organisms are needed to reproduce an offspring? 3. Does the offspring only have similarities in just one parent? Support your answer.
- 36. Learning Are 5:Fragmentation “A New Worm By Cutting?” (Watch a video clip about cutting a segmented worm into two parts.) 1. Observe and study the video clip. What organism is it? 2. What happened to the worm when it was cut? 3. What happened to the separated part of the worm? 4. How many parents are needed for the reproduction? 5. Does the offspring have similarities with the parent worm? Support your answer.
- 38. EXPLAIN • Let usexamine and hear your observations in the activity. • Each group shall have a designated speaker to present what they have observed in the learning area. • Each group will only present their observations in the first learning area that they visited.
- 39. • What haveyou observed in the parents of the different offspring. Do they have the same number of parents? • Why does it happen? • Does every offspring look exactly the same like their parents?
- 40. • There aretwo kinds of reproduction. Sexual and asexual reproduction. • SEXUAL REPRODUCTION needs two parents, the male and the female parent, to produce an offspring. It requires sperm and an egg cell to unite and form a zygote. It produces offspring that have features and properties different from their parent organism. • Example of sexual reproduction in plants is Pollination.
- 41. • Pollination- thetransfer of pollen grains from the anther to the stigma of a flower • The pollen grain that lands on the stigma develops a pollen tube that grows down through the style and into the ovary where the ovule is located. The sperm travels down the pollen tube and fertilizes the egg cell inside the ovule. The fertilized egg called the zygote develops into the embryo. The ovule becomes the seed. The ovary swells up and ripens to form a fruit. Inside the seeds plant embryo is located. This process is called FERTILIZATION.
- 43. • Animals alsoreproduce sexually. • Examplesare the dogs, goats, cows, carabaos and chicken.
- 45. ASEXUAL REPRODUCTION • Asexualreproduction, on the other hand, requires only one parent and there is no needs for the union of an egg and a sperm cell. It produces offspring that have features and properties the same as their parent organism.
- 46. Example of AsexualReproduction in Plants • a. Vegetative Reproduction-a reproduction in plants that involves plant parts such as stem, tube, rhizome, bulb and leaves.
- 48. • Examples ofplants that grow through vegetative propagation: • potato, garlic, ginger, cassava, carrots, ube, camote
- 49. b. Spore Formation-this involves the production of spores, which are specialized asexual reproductive cells. Examples are ferns.
- 50. ASEXUAL REPRODUCTION • Kindsof asexual reproduction in animals: • a. Binary Fission- The individual divides into two halves, after which each grows to the original form • Example: Paramecium
- 52. • b. Budding Theparent organism produces offsprings by growing a replica in the form of an outgrowth called a bud in some parts of its body. After it has grow enough, it falls off and becomes an exact copy of its parent Example: Hydra and Sponges
- 54. • c. Fragmentation Separatedpieces of the parent organism can develop into an individual. Examples: starfish, flatworm
- 58. ELABORATE Task No. 1SPOT THAT REPRODUCTION • I am Luzon Sea Star. I am breaking into two! What could be my mode of reproduction?
- 59. Task No. 2SPOT THAT REPRODUCTION • I am a Sponge! Having an outgrowth that separated from me. What could be my mode of reproduction?
- 60. Task No. 3SPOT THAT REPRODUCTION • My name is Molly! My then little baby have grown up. What could be my mode of reproduction?

- 63. • Now, whydo organisms need to reproduce? • Importance of Reproduction: • 1. Procreation- for continuous existence of organisms • 2. Quality Improvement- mixing of genetic materials leading to variation among individuals in a species
