Multiple Choice
Prokaryotes and eukaryotes share which of the following cellular structures?
A
Mitochondria
B
Nucleus
C
Ribosomes
D
Endoplasmic reticulum
Verified step by step guidance
1
Understand the basic differences between prokaryotic and eukaryotic cells. Prokaryotes are unicellular organisms that lack a nucleus and membrane-bound organelles, while eukaryotes have a nucleus and various membrane-bound organelles.
Identify the cellular structures listed in the problem: mitochondria, nucleus, ribosomes, and endoplasmic reticulum.
Recall that mitochondria, nucleus, and endoplasmic reticulum are membrane-bound organelles, which are typically found in eukaryotic cells but not in prokaryotic cells.
Recognize that ribosomes are non-membrane-bound structures responsible for protein synthesis and are found in both prokaryotic and eukaryotic cells.
Conclude that the cellular structure shared by both prokaryotes and eukaryotes is ribosomes, as they are essential for protein synthesis in all living cells.
