cytoplasm (of a cell)

The cytoplasm is the gel-like substance inside a cell that surrounds and supports the cell’s internal structures, known as organelles. It is primarily made up of water, salts, and proteins, providing a medium for various chemical reactions essential for cell function. The cytoplasm helps maintain the cell's shape, enables the movement of materials within the cell, and plays a role in processes like growth and energy production. Essentially, it acts as the cell’s internal environment where activities necessary for life occur.
