| | The number of cotyledons present in an embryo is an important character in the classification of flowering plants (angiosperms). | | | Structure in the embryo of a seed plant that may form a ‘leaf&; after germination and is commonly known as a seed leaf. | | | In seeds that also contain endosperm (nutritive tissue), the cotyledons are thin, but where they are the primary food-storing tissue, as in peas and beans, they may be quite large. |
