Plant Reproduction

a) Sexual reproduction in flowering plants involves:

• the production of male and female gametes
• the transfer of the male gametes to the female ovules in a process called pollination
• fertilisation, after which ovules grow into seeds within a fruit. 

b) The processes involved in sexual reproduction include:

• the anther produces the male gametes in pollen grains 
• the pollen grains attach to the stigma on top of a carpel, in which the female gametes (ovules) are located
• a pollen tube grows through the carpel's style into the ovule
• the nuclei from the pollen grain migrate into the ovule to fertilise the egg cell nucleus and endosperm nuclei
• the resulting zygote develops into an embryo
• the endosperm and the female tissues of the ovule give rise to seed
• the ovary then grows into a fruit, which surrounds the seed(s).
