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 act as a food reserve and contain the stored food of the seed. This stored food is utilized to help the embryo during seed germination. As these food reserves get exhausted, the cotyledon turns green and begins photosynthesis, or it may vanish gradually.

Detailed explanation-4: -Cotyledon refers to the significant part of the embryo found within the seed. It is the first and the tender leaf that emerges when the seed germinates. It is also called the storage unit of a seed, as it provides nutrients to the different parts of an embryo.
