cell - (pronounced) (sel) In biology, the smallest unit capable of living on its own, of which all living organisms and the tissues of the body are made. A cell consists of three main parts: the cell membrane, the nucleus and the cytoplasm. The cell membrane surrounds the cell and controls the substances that enter and leave the cell. The nucleus is a structure within the cell that contains the nucleolus and most of the cell's DNA. This is also where most RNA is made. The cytoplasm is the fluid inside the cell. It contains other tiny cell parts that have specific functions, including the Golgi complex, mitochondria, and endoplasmic reticulum. In the cytoplasm, most chemical reactions take place and most proteins are made. The human body has more than 30 trillion cells
