- 16. POLLINATION SEXUAL REPRODUCTION Female cell Male cell The result?
- 17. 1. Insects and small birds pick up pollen.
- 19. 2. They transport it from the stamen to the pistil.
- 21. 3. Some of the pollen sticks to the stigma
- 23. 4. From the stigma, the pollen travels down to the ovary.
- 25. 5. Here, the pollen fertilises the ovules.
- 26. Male cell in pollen Female cell= ovule
- 27. 6. The fertilised ovules develop into seeds.
- 28. SEEDS
- 31. 7. When the flower dies, the seeds are spread.

- 61. Formula of photosynthesis MINERALS WATER + SOLAR ENERGY CARBON DIOXIDE + GLUCOSE + O2 XYLEM PHLOEM
- 62. Why is photosynthesis so important? 1. Plants give us food. 2. They give us oxygen. 3. They absorb carbon dioxide, which cause global warming. 4. They provide habitats and food for other
- 63. Why is photosyntheis so important? 1. Plants give us food.
- 64. Why is photosyntheis so important? Plants give us oxygen.
- 65. Why is photosyntheis so important? Plants absorb carbon dioxide, which cause global warming.
- 66. Why is photosyntheis so important? Plants provide habitats for animals.
- 67. To remember Xylem: transports water and minerals Phloem: transports glucose Rhizome: stems underground Tubers: thick stems underground
