13. Hypocotyl
• The hypocotyl (short for
"hypocotyledonous stem",
meaning "below seed leaf") is
the stem of a germinating
seedling, found below the
cotyledons (seed leaves) and
above the radicle (root).
14. Epicotyl
• the epicotyl is the embryonic
shoot above the cotyledons. In
most plants the epicotyl will
eventually develop into the
leaves of the plant.
15. Radicle
• the radicle is the first part of a
seedling (a growing plant
embryo) to emerge from the
seed during the process of
germination
16. Cotyledon
• A cotyledon is a significant part
of the embryo within the seed of
a plant. Upon germination,
the cotyledon may become the
embryonic first leaves of a
seedling.
17. Endosperm
• Endosperm is the tissue produced inside 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.
18. Embryo
• the part of a seed that develops into a plant,
consisting (in the mature embryo of a higher
plant) of a plumule, a radicle, and one or two
cotyledons.
19. Seed coat
• A seed is an embryonic plant enclosed
in a protective outer covering called
the seed coat, usually with
some stored food.
