Animal cell. Transmission electron micrograph of a mammalian tissue culture cell. Taking up most of the cell is the nucleus,where genes are stored in the form of chromosomes. The dark zone (centre right) in the nucleus is the nucleolus. This is the most active part of the nucleus,and contains unravelled chromosomes involved in making protein-manufacturing bodies called ribosomes. Outside the nucleus is the cell cytoplasm. The dark grey bodies in the top of the cell are mitochondria. These supply the cell with energy. The white areas are membrane-bound vesicles or air bubbles introduced during sample preparation.
