Class - Dicotyledon. Division is divided into two classes, 'monocotyledon' or 'dicotyledon'. Cotyledon means 'seed leaf'. Monocotyledons are plants which have veins parallel to the leaf margins and a single leaf after germination (e.g. grasses).

Dicot - also dicotyledon; flowering plants with embryos that have two cotyledons. Dioecious - plants that have only male or only female flowers on an individual plant. Disease resistance - the tendency not to be infected by a particular pathogen.

In monocotyledons, the seed contains only one seed leaf and in dicotyledons it has two. In monocots, such as grasses, the single cotyledon remains inside the seed and acts as a digestive organ for the embryo.

Just above them are the seed leaves or dicotyledons. And above those will be the first two true leaves.
