How Cotyledons Are Useful For The Plant?

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.

What are cotyledons in plants?

Cotyledons are the first leaves to develop on a plant after it has germinated.Cotyledons are frequently referred to as ″seed leaves″ rather than ″real leaves″ since they are truly a component of the seed or embryo of the plant, and hence are not regarded to be ″genuine leaves.″ The purpose of the seed leaves is to gain access to the nutrients that have been stored in the seed so that they can nourish the seed until the actual leaves form and begin the process of photosynthesis.

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.

How long do cotyledons remain under the soil?

In a similar manner, the hypogeal cotyledons, which are the parts of the seed that remain buried in the soil, are also responsible for channeling the energy that has been stored in the seed.These cotyledons will wither when they are no longer required.Although the cotyledons of certain plants can remain for up to a week, the vast majority of them have fallen off by the time the first two genuine leaves have emerged.
