Cotyledons are important because they store nutrients that support the growth of the embryo in a seed. They provide essential energy and nutrients for the seedling to germinate and establish itself until it can produce its own food through photosynthesis. Additionally, cotyledons can vary in shape and function depending on the plant species, with some serving as the first leaves of the seedling.
A part of a seed which is inside the seed coat is called cotyledon and it contains EMBRYO and the stored food
The cotyledon is broken down by enzymes within the seed during germination. These enzymes help to digest stored nutrients within the cotyledon, providing essential energy and building blocks for the developing seedling.
When single cotyledon develops from the fertilized egg during embryogenesis, the resultant seed is a monocot.
A fern leaf can be called a frond. (The same word is also used for palm leaves.)
Cotyledon is also known as seed leaf. It is the first leaf or pair of leaves produced by the embryo of a seed plant.
