DENDROLOGY

Detailed explanation-1: -cotyledon, seed leaf within the embryo of a seed. Cotyledons help supply the nutrition a plant embryo needs to germinate and become established as a photosynthetic organism and may themselves be a source of nutritional reserves or may aid the embryo in metabolizing nutrition stored elsewhere in the seed.

Detailed explanation-2: -A cotyledon stores food for the seed which it uses during the process of germination. Cotyledons also form the first leaves in a baby plant.

Detailed explanation-3: -Cotyledons are known as “seed leaves” because they emerge and turn green as the seed germinates. Cotyledons provide nutrients to the plant embryo in order to germinate and sustain themselves as a photosynthetic creature.
