Cytoplasm is a jelly-like substance found inside cells, filling the space between the cell membrane and the nucleus. It is primarily made up of water, salts, and proteins, and it plays a crucial role in supporting the cell's structure. The cytoplasm contains various organelles, such as mitochondria and ribosomes, which perform essential functions for the cell's survival and operation. In addition to providing a medium for chemical reactions, the cytoplasm helps transport materials within the cell. It allows nutrients to move to different parts of the cell and waste products to be removed. Overall, cytoplasm is vital for maintaining the cell's health and functionality.
