Endosperm is a unique tissue found in angiosperm seeds that serves as a source of nutrition for the developing embryo. It is formed during double fertilization when one sperm cell fuses with the egg cell to form the embryo, while the other sperm cell fuses with the central cell to form the endosperm. The endosperm typically contains a high concentration of nutrients such as carbohydrates, proteins, and lipids, which are essential for the growth and development of the plant embryo.
The endosperm plays a crucial role in providing energy and nutrients for the developing embryo until it can establish its own root system and begin photosynthesis. In some plant species, such as corn, the endosperm is the main source of nutrition for the growing seedling until it can establish its own nutrient uptake system. Overall, the endosperm is a key component of seed development and plant growth, ensuring the successful germination and establishment of new plants.#16#
