Question

which statement is the best description of a seed. an embryonic plant surrounded by a starch source encapsulated in a covering. an enlarged starch/sugar layer surrounding the fertilized ovary of a flower that has desiccated and formed structure we refer to as a seed. after pollination the fertilized ovum forms the seed from phloem tissue. a small structure that results from asexual reproduction which produces an encapsulated set of chromosomes.

Explanation:

A seed's core structure is an embryonic plant, which is supplied with a nutrient source (often starch-rich endosperm or cotyledons) and protected by a seed coat (encapsulating covering). The other options are incorrect: seeds form from fertilized ovules (not ovaries, which become fruit), not phloem tissue, and are the product of sexual (not asexual) reproduction.

Answer:

An embryonic plant surrounded by a starch source encapsulated in a covering.
