AI overview
The cytosol is the clear, liquid part inside cells that contains dissolved molecules and fills up to 30% of the space in the cytoplasm. It matters because many essential cellular activities happen in this crowded molecular environment, making it crucial for how cells function.

thumb|right|300px|The cytosol is a crowded solution of many different types of molecules that occupy up to 30% of the cytoplasmic volume.
The cytosol, also known as cytoplasmic matrix or groundplasm, is one of the liquids found inside cells (intracellular fluid (ICF)). It is separated into compartments by membranes. For example, the mitochondrial matrix separates the mitochondrion into many compartments.
