Question

both prokaryotic and eukaryotic cells have
a nucleus
cytoplasm
mitochondria
specialized organelles

Explanation:

To determine the correct answer, we analyze each option:

• Option A (a nucleus): Prokaryotic cells lack a true nucleus, while eukaryotic cells have one. So this is not present in both.
• Option B (cytoplasm): Both prokaryotic and eukaryotic cells have cytoplasm, which is the gel - like substance within the cell where many cellular processes occur.
• Option C (mitochondria): Prokaryotic cells do not have mitochondria (they are organelles found in eukaryotic cells for energy production).
• Option D (specialized organelles): Prokaryotic cells have few or no specialized organelles compared to eukaryotic cells which have many (like endoplasmic reticulum, Golgi apparatus etc.).

Answer:

B. cytoplasm
