What is the Number of Cotyledons in the Embryo of Pinus?
Pinus is a genus of conifer trees that belongs to the family Pinaceae. It is one of the most abundant and widespread genera of trees in the world. Pinus species are found in most of the world’s temperate regions, from the Arctic circle to the tropics.
What are Cotyledons?
Cotyledons are embryonic leaves found in the seed embryo of flowering plants. They are the first leaves to develop and provide food for the newly formed seedling. A seedling typically develops two cotyledons, which are usually similar in shape, size, and color.
Cotyledons in the Embryo of Pinus
In the embryo of Pinus, the number of cotyledons is two. These two cotyledons are known as megagametophytes. The megagametophytes are large and contain a large amount of food material. They are responsible for the nutrition and growth of the seedling.
