cotyledon

Modified leaf ('seed leaf'), found as part of the embryo in seeds, involved in either storage or absorption of food reserves. Dicotyledonous seeds contain two, monocotyledonous seeds only one. May appear above ground and show photosynthetic activity in the seedling.

Cotyledon

Seed leaf: leaf-like structures in the embryos of seeds. Grasses have one cotyledon in each seed (monocotyledon), while legumes have two (dicotyledon).
