Detailed explanation-1: -The cotyledons of the dormant mustard embryo contain large amounts of fat serving as a source of energy and carbon during the early period of seedling development, which is characterised by a purely dissimilatory energy production.

Detailed explanation-2: -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-3: -Seedling: Plants propagated from any form of germplasm. Seed source: Individual trees or stands, natural or planted, from which seed is collected. This manual addresses four types of seed sources: seed trees, seed stands, seed production areas and seed orchards. Seed trees: Trees from which seed is collected.

Detailed explanation-4: -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.
