3.4 Reproduction in Plants
- Can you explain with examples, how plants can reproduce asexually by natural and artificial methods?
- Can you label diagrams of an insect-pollinated and a wind-pollinated flower, and explain how each is adapted for pollination?
- Can you explain the processes following pollination including growth of the pollen tube, fertilisation, and seed and fruit formation?
- What conditions are needed for seed germination?
- What enables a germinating seed to grow before it can carry out photosynthesis?
