Endosperm

Image

 

Although the circular object in the photograph above may seem obscure, this object is a common seed from a fruit. Seeds are made up of many different parts that serve for care and nourishment. Inside the seeds of most flowering plants, a natural tissue called an endosperm forms and develops around the time of fertilization. The endosperm serves the purpose of providing nourishment in the form of starch, oil, and protein to the enclosed embryo. The endosperm surrounds the embryo completely. Endosperms can form in a variety of different ways including heloial, cellular, and nuclear endosperm formation. After fertilization, the endosperm begins to serve as a storage mechanism in some seeds. On the other hand, some seeds do not even produce endosperm.
