The cotyledons contain (or in the case of gymnosperms and monocotyledons, have access to) the stored food reserves of the seed. As these reserves are used up, the cotyledons may turn green and begin photosynthesis, or may wither as the first true leaves take over food production for the seedling.
Also, what is cotyledon in plant?
Cotyledon, seed leaf within the embryo of a seed. Flowering plants whose embryos have a single cotyledon are grouped as monocots, or monocotyledonous plants; embryos with two cotyledons are grouped as dicots, or dicotyledonous plants.

Why cotyledons are called seed leaves?
Cotyledons are not considered true leaves and are sometimes referred to as “seed leaves,” because they are actually part of the seed or embryo of the plant. 1 The seed leaves serve to access the stored nutrients in the seed, feeding it until the true leaves develop and begin photosynthesizing.
