What nourishes angiosperm embryos?

Answer 1

Angiosperm embryos are nourished primarily by endosperm, a tissue formed during fertilization that provides essential nutrients. The endosperm stores carbohydrates, proteins, and fats, which support the developing embryo as it grows. Additionally, the surrounding seed coat can also play a role in protecting and providing some sustenance until the embryo is ready to germinate. This nutrient supply is crucial for the successful establishment of the plant once it begins to grow.
