Cotyledonous, also known as cotyledonary or cotyledonate, is an adjective used to describe plants that have cotyledons. Cotyledons, commonly known as seed leaves, are the embryonic leaf structures found in the seeds of flowering plants. They are typically the first leaves to emerge from the seed upon germination.
Plants that are cotyledonous belong to one of the two main groups of flowering plants: monocots and dicots. Monocots have one cotyledon, while dicots have two. The cotyledons play a vital role in providing nourishment to the developing plant embryo until it can photosynthesize on its own. They store and transport nutrients such as proteins, sugars, and vitamins.
Cotyledonous plants are characterized by their ability to produce primary leaves, called true leaves, after the cotyledons have fulfilled their purpose. True leaves are usually more complex in structure and function compared to cotyledons. Upon the development of true leaves, the cotyledons often wither and fall off, as they are no longer needed.
Cotyledonous plants include a wide range of species, from small annual herbs to towering trees. They are an essential component of ecosystems, providing food and habitat for various animal species. Additionally, many cotyledonous plants also have economic significance as crops and ornamentals, contributing to agriculture, horticulture, and other industries.
In conclusion, cotyledonous refers to plants that possess cotyledons, which are vital in the early stages of plant development and play a significant role in storing and transporting nutrients.

The word "cotyledonous" is derived from the combination of two words: "cotyledon" and the suffix "-ous".
"Cotyledon" comes from Greek roots. The Greek word "kotylēdōn" (κοτυληδών) means "cup-shaped cavity" or "a cavity for a bowl". It is composed of "kotyle" (κοτύλη), meaning "cup" or "bowl" and "eidos" (εἶδος), meaning "form" or "shape".
The suffix "-ous" is a Latin suffix that is used to form adjectives. It means "full of" or "possessing the qualities of".
Therefore, "cotyledonous" describes something that possesses or has the qualities of "cotyledons".
