Plant ovules: Gymnosperm ovule on left, angiosperm ovule (inside ovary) on right

Endosperm

Endosperm is the tissue produced in the seeds of most flowering plants around the time of fertilization. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein.

Radicle

The radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination. The radicle is the embryonic root of the plant, and grows downward in the soil.

Plumule

The plumule is the embryonic shoot. It is the precursor to the stem and leaves of the plant.
