What are the functions of cotyledons?

Cotyledons are seed leaves that store or absorb food and nourish the developing embryo during germination.

Their main functions are:

• Store food for the embryo (in many seeds)

• Absorb nutrients from the endosperm

• Supply energy during germination

• Sometimes perform photosynthesis after germination

Quick Fact: Monocot seeds have one cotyledon, while dicot seeds have two cotyledons.
