Sexual reproduction in plants relies on the fusion of male and female gametes, which are haploid cells containing half the species' genetic material. The male gametes are contained within pollen grains formed in the [1].

For fertilisation to occur, pollination must first take place, transferring pollen to the sticky [2] of the carpel.

Once deposited, the pollen grain germinates and grows a long [3] down the [4] towards the ovary.

This structure enters the [5] through a tiny pore called the micropyle.

Here, the male gamete fuses with the female egg cell in a process called [6], which produces a diploid [7].

Following this, the ovule develops into a [8] while the surrounding ovary wall matures into a fruit.
