flower
A cross-section of a flower showing sexual parts.

Most flowers contain both male and female parts.

The male parts, stamens, bear anthers that produce the male sex cells or pollen grains. The female part consists of the ovary which produces the female sex cells or ovules.

A seed is a fertilized ovule, that is formed as a result of the union between the male and female gametes, in a process called fertilization.

fertilization
Fertilization – the pollen grows down the style to fuse with the ovule. The zygote then divides after fusion to form the embryo, while the ovule develops into a seed.
