1. Sexual and Asexual Reproduction Life Science Mr. P

2. Note ***This is not a presentation on human reproduction. That discussion and information will be later in February

3. Asexual Reproduction This is where a single organism will reproduce by itself, through mitosis, fragmentation, or cell division. It does not involve egg or sperm.

4. Asexual Reproduction Organism that reproduces asexually: – Bacteria – Some fish – Some plants – Worms – Single cell protists

5. Sexual Reproduction Involves the joining of egg (from female) and sperm (from male). This is called fertilization.

6. Flowers Life Science

7. Plants Some plants have reproductive structures called flowers

8. Flowers Stamen is the male part of a flower, which has the pollen (plant’s sperm cells)

9. Flowers Pistil is the female part of a flower, which has the ovule. The ovule holds the plant’s egg cells

10. Flowers The flower uses petals to attract pollinators (like birds and insects) to the flowers.

11. Flowers Pollination is when a pollen grain lands on a flower's pistil, and the pollen grain then grows a pollen tube to the ovule.

13. Life Cycle of Plants Mr. P Life Science

14. The seed The seed develops into a baby plant.

15. The seed Many times the seed is surrounded by a fruit, so that it can develop and be deposited on the ground under the right conditions and in different places.

16. The seed The seed then develops and grows into a plant when the conditions are right.
