Parts of a Seed

Diagram of a seed The seed contains the embryo of the new
plant, with a supply of food for the embryo
until it has formed sufficient roots and leaves
to obtain its own food. The food, endosperm,
may be in the seed leaves or it may be
outside the seed leaves and be absorbed
when the seed germinates.

To start germination, the seed leaves
absorb water and swell, and the radicle
emerges, followed by the plumule.
