Cotyledons
The grasses and narrow-leaved plants like the iris and bluebell have seeds with only one cotyledon. The other flowering plants all have two cotyledons. They are leaves attached to the plumule and radicle by short stalks, and they often contain food reserves which are used during the early stages of germination. In most plants the cotyledons are brought out of the testa and above the ground where they become green and make food by photosynthesis. The cotyledons eventually fall off, usually after the first foliage leaves have been formed. The cotyledon leaves bear no resemblance to the foliage leaf, the shape of which is first apparent when the plumule leaves open and grow.
