cytosol

Cytosol is the jelly-like, transparent fluid that fills the inside of a cell, surrounding its structures and organelles. It is mainly made up of water, but also contains salts, enzymes, and other molecules essential for cellular functions. The cytosol provides a medium for chemical reactions to occur and helps transport nutrients, ions, and waste within the cell. It supports the cell's internal environment, maintaining proper conditions for life processes, and plays a crucial role in cell growth, signaling, and metabolism.
