Question

What are cotyledones? State its functions in seed?

Answer 1

Cotyledons are the first part of a plant to emerge from the seed. They are formed within the seed along with the endosperm. Botanists classify plants based on the number of cotyledons they have. Cotyledons function to provide the initial growth for the plant and as an energy source.

Answer 2

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. The number of cotyledons present is one characteristic used by botanists to classify the flowering plants (angiosperms). Species with one cotyledon are called monocotyledonous (or, "monocots") and placed in the class Liliopsida. Plants with two embryonic leaves are termed dicotyledonousdicots and placed in the class Magnoliopsida.
