What are Cotiledones?

Cotiledones are structures found in the seeds of angiosperm plants, also known as flower plants. They play a key role in the initial development of plants, providing nutrients and energy for the growing embryo.

Cotiledones Function

Cotiledones are responsible for storing and providing essential nutrients for the embryo during seed germination. They are rich in substances such as starch, proteins and lipids, which are used as a source of energy for the initial growth of the plant.

In addition, cotyledons also play an important role in water absorption and embryo protection against mechanical damage and dehydration.

Types of Cotiledones

There are two main types of cotyledons: monocotyledons and dicotyledons.

Monocotyledon plants have only one cotyledon in their seeds. Examples of monocotyledon plants include grasses such as corn and rice, and ornamental plants such as lilies.

Dicotyledon plants have two cotyledons in their seeds. Examples of dicotyledon plants include beans, pea, sunflower and many fruit trees.

Importance of Cotiledones

Cotiledones are essential for the initial development of plants as they provide the nutrients needed for the growing embryo. They are the first source of food of the plant until it is able to perform photosynthesis and produce its own food.

In addition, cotyledons also play an important role in water absorption and embryo protection against external damage.
