Endosperm is a tissue found in plant seeds that serves as a primary source of nutrients for the developing embryo. It is rich in proteins, carbohydrates, and lipids, providing essential energy for the germinating seedling. The endosperm is formed during fertilization when the male gamete fuses with the central cell of the female gamete. This fusion results in the formation of a triploid cell, which develops into the endosperm.
One of the key functions of the endosperm is to nourish the developing embryo until it can establish its own photosynthetic capabilities. In some plants, the endosperm is consumed by the embryo during germination, while in others, it remains as a nutrient reserve throughout the plant’s life cycle. The endosperm also plays a role in regulating seed dormancy and germination, ensuring the successful growth and development of the plant.
In conclusion, endosperm is a crucial component of plant seeds that provides essential nutrients for the developing seedling. Its role as a nutrient reserve is vital for the successful germination and growth of plants.#16#
