DENDROLOGY

Detailed explanation-1: -In a dicotyledonous seed, the embryo consists of an embryo axis and two cotyledons. Cotyledons generally have a swollen appearance as it acts as a food reserve for the developing seedling. The embryo axis has two ends.

Detailed explanation-2: -Plants producing seeds with two cotyledons are called dicots. The cotyledons contain stored fat that nourishes the embryo. While, plants having a single cotyledon in their seeds are called monocots.

Detailed explanation-3: -Angiosperms (flowering plants) whose embryos have a single cotyledon are grouped as monocots, or monocotyledonous plants; most embryos with two cotyledons are grouped as eudicots, or eudicotyledonous plants.
