how flowers make seeds
When pollen lands on a flower’s stigma, a tube grows down to the
ovule. Here it joins an egg to make a seed. The fruit forms around the
seed.
What a flower does
A flower’s job is to make seeds.
The stigma, which is often covered with a sticky fluid, is in the middle
of a flower. Around it are one or more tiny stems with knobs on top.
These knobs are called anthers. Inside the anthers is a dust called
pollen, which is usually golden.
For a flower to make seeds, pollen from one flower must fall on the
stigma of the same kind of flower. A tiny tube then grows out of the
pollen and pushes down into a part of the flower called the ovule. A
tiny egg is in the ovule.
The ovule now grows into a seed. Inside the seed, the egg becomes a tiny
plant. The fruit forms around the seed.
