We have heard that seeds are high in protein. If we were to cut open a seed and look for this store of protein under the microscope ,in which cellular structure might we find it? Why does a seed need this store of protein?

Step-by-step answer

P Answered by PhD

Need this store of protein:

The seed consists of three components: embryo, endosperm (sometimes perisperm), and seed-coat. Both endosperm and embryo are the products of double fertilization, whereas the seed-coat develops from the maternal, ovular tissues. The seed habit is a significant advancement in the evolution of higher plants.
