Q
How do plants reproduce
A
Pollen lands on stigma
Pollen tube grows through flower tissue until it reaches the ovule
Pollen grain nucleus travels through the tube and fuses with the ovule nucleus
After fertilisation the femal parts of the flower develop into the fruit
Ovules become seeds
Ovary becomes the rest
