Cotyledons contribute to the provision of the nourishment a plant embryo requires in order to germinate and become established as a photosynthetic organism. Cotyledons may themselves be a source of nutritional reserves or may assist the embryo in metabolizing nourishment stored in other parts of the seed.
The cotyledon is a leaf-like structure that develops within the embryo of a seed.

What is a cotyledon?
Find out what a cotyledon is, what it does, and the difference between plants with two leaves, which are called dicots, and plants with just one leaf, which are called monocots. Date of last update: 10/16/2021 What exactly is a cotyledon, then? What exactly is a cotyledon, then? Around 125 million years ago, a class of flowering plants known as angiosperms started to develop.
What happens to the cotyledon after the first leaves appear?
Cotyledons that can undertake photosynthesis will continue to be present on the plant even after the first real leaves have emerged and taken their place.In most cases, this just takes a few days, and then the seed leaves will shed their leaves.They continue to exist in order to assist in directing the energy that is stored in the seed toward new development, but once the plant is capable of providing for its own needs, they are no longer required.
What is the number of cotyledons in a seed?
The cotyledon is a leaf-like structure that develops within the embryo of a seed.Embryos of flowering plants that are classified as monocots, also known as monocotyledonous plants, are distinguished from embryos of dicot, also known as dicotyledonous plants, by the presence of a single cotyledon rather than two.There is a wide range of variation in the number of cotyledons that may be found in the embryos of gymnosperm seeds, anywhere from eight to twenty or more.
