The structure designed for food absorption and storage in plant embryo is called the cotyledon. Cotyledons are seed leaves that are present in the embryo of a seed plant. They are the first leaves that emerge from the seed during germination and serve as a source of nourishment for the developing seedling until it is able to produce its own food through photosynthesis. Cotyledons are typically fleshy and contain stored food reserves such as starch, proteins, and oils. The number of cotyledons present in a seed can vary depending on the plant species, with some plants having one cotyledon (monocotyledons) and others having two cotyledons (dicotyledons).
