  • Cells
    Basic unit of life. Unicellular organisms only have one cell. Multicellular organisms have many cells that work together.
  • Animal cell structure

    • Nucleus
    • Cell membrane
    • Cytoplasm
    • Mitochondria
  • Plant cell structure

    • Chloroplasts
    • Cell wall
    • Large central vacuole
  • Cell components and their functions

    • Cell membrane - Controls the movement of substances into and out of the cell
    • Cytoplasm - Jelly-like substance, where chemical reactions happen
    • Nucleus - Carries genetic information and controls what happens inside the cell
    • Mitochondria - Where respiration takes place, releasing energy for the cell
    • Large central vacuole - Contains a liquid called cell sap, which keeps the cell firm
    • Cell wall - Made of a tough substance called cellulose, which supports the cell
    • Chloroplasts - Contain the green pigment chlorophyll, which absorbs light energy. This is where photosynthesis occurs
