Taking food through its stalk, the developing seed expands its endosperm and embryo. When the embryo is mature and dormant, the integuments develop into a protective seed coat and detach from the ovary wall. The main axis of the embryo has a root apex and a short stem that may have a few tiny leaves near the shoot apex. The cotyledons are part of the embryo; they're the first leaves. Monocots have one cotyledon; eudicots have two.
