These compartments are usually isolated from the rest of the cytoplasm through intracellular membranes. These membranes could be similar to the plasma membrane or made from a different complement of lipids and proteins. The properties of a membrane are due to its origin, such as with mitochondria or plastids, or due to its specific function ... Learn about organelles in cell biology.
