Detailed explanation-1: -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: -Answer and Explanation: The answer is yes, the cotyledon stores food for the baby plant inside the seed. 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.
Detailed explanation-3: -Cotyledons are a part of the embryo within seeds that form the first leaves when the plant germinates. They contain stored food that helps provide the initial energy that the plant needs to grow.
Detailed explanation-4: -The seeds that store their food in cotyledons are known as non-endospermic seeds. they are also called exalbuminous seeds. As legumes are seeds with two cotyledons, they are known as dicotyledons, they store their food in their cotyledon and not in the endosperm. Hence they are called exalbuminous seeds.
