  • Cells
    • animal and human cells contain:
      • a nucleus
        • controls the activities of the cell
      • cytoplasm
        • where most of the chemical reaction take place
      • A cell membrane
        • controls the passage of substances in and out of the cell
      • mitochondria
        • where most of the energy is released in respiration
      • ribosomes
        • where protein synthesis takes place
      • Enzymes control the chemical reactions inside cells
        • Plant cells contain
          • a nucleus, mitochondria, cytoplasm, a cell membrane and ribosomes
          • Chloroplasts
            • absorb light energy to make food through photosynthesis
          • A permanent vacuole
            • filled with cell sap, is used to keep cells rigid to support the plant
          • A cell wall
            • made of cellulose which strengthens the cell and gives it support

    • Specialised cells
      • Bacteria cell
        • Cytoplasm, a cell wall membrane and a cell wall
        • Genetic material NOT in a distinct nucleus
      • Carry out particular functions
      • Yeast cell
        • Nucleus, cytoplasm, cell membrane and a cell wall
      • Sperm cell
      • Egg cell
