It has been proposed that mitochondria and chloroplasts are modern descendants of early prokaryotic cells that began to reside and gradually evolve within primitive cells. which statement supports this view? a) mitochondria and chloroplasts both have prokaryotic ribosomes b) mitochondria and chloroplasts cannot conduct protein synthesis c) prokaryotic cells, mitochondria, and chloroplasts are void of any dna d) mitochondria and chloroplasts are found in all modern prokaryotic cells

The mitochondria and chloroplasts are the modern descendants of the early prokaryotic cells. These resided in the primitive cells and then evolved with them as a part of them. This hypothesis is supported by the fact that both the mitochondria and chloroplasts contain their own primitive ribosomes. Both these organelles have the 70s ribosomes.

Hence, the correct answer is 'option A - mitochondria and chloroplasts both have prokaryotic ribososmes'.
