- 1.(b) The transfer of pollen from the anther to the stigma
- 2.(c) Dandelion
- 3.(b) The fusion of a pollen nucleus with an egg cell in the ovule
- 4.(c) By insects
- 5.A new plant / seedling
- 6.The coconut has a fibrous, waterproof husk that traps air and allows it to float
- 7.(b) Pollen transferred from the anther to the stigma of the same flower
- 8.(c) The drying and splitting of the fruit pod
- 9.Male: stamen (anther and filament); Female: carpel/pistil (stigma, style, and ovary)
- 10.They do not need to attract insects; wind disperses pollen, so colourful petals and nectar are unnecessary
