Answer 2

Answer:

$]\huge\red{\mathfrak{Answer:-}}$

• Seed, the characteristic reproductive body of both angiosperms (flowering plants) and gymnosperms (e.g., conifers, cycads, and ginkgos).

• Essentially, a seed consists of a miniature undeveloped plant (the embryo), which, alone or in the company of stored food for its early development after germination, is surrounded by a protective coat (the testa).

• A layer of nutritive tissue in the seed of certain flowering plants that are derived from the nucellus and surrounds the embryo.

• In seeds of some plants remnants of a nucleus is persistent. This residual, persistent nucellus is called perisperm.
