CELLS AND CELLS PHYSIOLOGY

The basic unit of all living things.
1. ANIMAL CELLS
  1. PARTS FUNCTION
    1. Nucleus: control centre of the cell.
      1. Cytoplasm: suspends all the cell organelles.
        Cell membrane: controls what enter and leave the cell.
        Mithocondrion: production of energy.
        Vacuole: used for storage.
        Ribosomes: makes proteins.
2. PLANT CELLS
  1. PARTS FUNCTION
    1. Nucleus: control centre of the cell.
      1. Cytoplasm: suspends all the cell organelles.
        Cell membrane: Controls what enter and leave the cell.
        Cell wall: surrounds and protects the cell.
        Chloroplast: converts sunlight into plants food.
        Vacuole: used for storage.
        Mithocondrion: production of energy.
        Ribosomes: makes proteins.
