Praxis II Biology

Answer: B, The cellular organelle found in both eukaryotes and prokaryotes is the ribosome. Ribosomes are the organelles that produce proteins for the cell.

Key Takeaway: Eukaryotic cells contain numerous membrane bound organelles, each of which performs a specific function. This increases the efficiency and productivity of those cells, which allows for the formation of more complex tissues and structures. Prokaryotes are extremely simple by comparison, composed mostly of cytoplasm. Their genetic material is not protected by a nucleus, and the only cellular organelle contained is the ribosome.
