Dicotyledon
Dicotyledon
Dicotyledon (pronunciation: /ˌdaɪkoʊtɪˈliːdən/), also known as dicots, is a group of flowering plants that are classified based on the number of cotyledons in the seed. The term "dicotyledon" comes from the Greek words "di" meaning two, and "kotyledon" meaning seed leaf.
Dicotyledons are one of the two major types of flowering plants, the other being monocotyledons. They are characterized by having two embryonic leaves or cotyledons, hence the name. Other distinguishing features of dicotyledons include a taproot system, reticulate venation in the leaves, and flower parts that are typically in multiples of four or five.
