  • B2 - Topic 2 - 1.3
    • Be able to describe the function of the components of an animal cell
    • Animal cells are much larger than bacterial cells, with important differences from plant cells.
    • Cell membrane:
      • The cell contents i.e. the cytoplasm, nucleus, vacuoles, mitochondria etc.
        • are all held together by the cell membrane which controls the passage of substances in and out of the cell.
    • Mitochondria
      • The energy releasing chemistry of respiration occurs in the mitochondria.
        • e.g. glucose + oxygen ==> carbon dioxide + water + energy
        • Mitochondria are power house of the cells and provides the chemical energy for any of the cells functions.
    • Cytoplasm
      • Cytoplasm is a jelly like fluid in which most of the cells chemical reactions take place.
    • Nucleus
      • The cell nucleus contains all the DNA of the genes in the chromosomes
        • This control the cells functions and the cell division of replication
      • The nucleus controls the activities of the cell by sending instructions to the cytoplasm.
    • Glycogen granules
      • Stored food for respiration.
