DENDROLOGY

Detailed explanation-1: -The endosperm, a nutritive tissue, formed during the double fertilization, supplies food material to the young embryo. Both the endosperm and cotyledons store food material.

Detailed explanation-2: -Cotyledons of seed are units to store reserve food in the form of fats and proteins which are used by young embryo after germination, during its initial growth as a seedling. Q. Cotyledon is the part of a seed that stores food for the embryo.

Detailed explanation-3: -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.

Detailed explanation-4: -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.
