Cytosol vs. Cytoplasm: Know the Difference

By Shumaila Saeed || Updated on December 25, 2023

Cytosol is the liquid part of the cytoplasm, whereas cytoplasm includes cytosol, organelles, and other cellular components.

Key Differences

Cytosol is the fluid portion of the cytoplasm, consisting mainly of water, salts, and organic molecules. Cytoplasm, on the other hand, includes the cytosol along with the organelles and other cellular substances.
