  • Organisms
    • Cells
      • Plant cells have a chloroplast containing chlorophyll for photosynthesis
      • Animal cells have a nucleus containing genetic material so does the plant cell.
    • Specialised cells
      • Examples such as: red blood cells, mucle cells, lilted cell, motor cell. (animal cells) or root hair cell and Xylem cell (plant cells)
      • simple molecule-> complex molecule->organelle-> cell-> tissue-> organ-> organ system-> organism
    • movement in and out of cells
      • diffusion: the movement of particles within a gas or liquid from a region of high concentration to a region of lower concentration until an equilibrium is reached
      • Osmosis: diffusion of water through a partially permeable membrane
      • in special cases -> phagocytosis
      • active Transport
