Does double fertilisation occurs both in monocots and dicots

Answer 1

Double fertilization occurs in both monocots and dicots. It is a unique feature of angiosperms, or flowering plants, where two sperm cells fertilize two different nuclei within the embryo sac.

In monocots, such as grasses and lilies, double fertilization also occurs, resulting in the formation of an endosperm and a zygote. The endosperm provides nutrients to the developing embryo, similar to the role of the cotyledons in dicots.

In dicots, such as beans and tomatoes, double fertilization also takes place, leading to the formation of an endosperm and an embryo. The endosperm serves as a source of nutrients for the developing seedling, while the embryo develops into the new plant.

Overall, double fertilization is a common and essential process in the reproductive cycle of both monocots and dicots.
