Since my darling Dean did not come to me before he started growing I did not get a picture of his seed, so this is a labeled photo of Dean's seed before he was put into the soil. It shows the cotyledons which are the leaves of the embryo that store food in the form of starch and protein. Because there are two cotyledons, the bean seed is considered a dicot seed.
The epicotyl is the stem of a seedling or embryo located between the cotyledons and the first true leaves and the hypocotyl is the part of the embryo below the cotyledons.
