Question

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.

Answer 1

mitochondria and chloroplasts both have prokaryotic ribososmes

Step-by-step explanation:

• Mitochondria and chloroplasts are the modern descendants of early prokaryotic cells. These lived in primitive cells and later developed into part of them.
• This hypothesis is supported because both mitochondria and chloroplasts have their own primitive ribosomes. These two organs contain 70s ribosomes.
