WebbThus, cell membranes regulate the concentration gradient and transfer the materials for the health and maintenance of their cells. Cell membranes help in holding the cytoskeleton in places. Often, few proteins extend their support and connect with cytoskeletal fibres to balance and define the shape of various cells. Webb12 apr. 2024 · Cytoplasm is a clear substance that is gel-like in the cell membrane but is on the outside of the nucleus. It contains mostly water with the addition of enzymes, organelles, salts and organic molecules. Cytoplasm will liquefy when it is stirred or agitated. It is often referred to as cytosol, meaning "substance of the cell."
