  • Cells tissue and organ
    • cell tissue and organisms
      • Animal and plant cells
        • Nucleus controls cell activity
        • Mitocondria     where energy is released
        • Cell membrane controls the movement of substances which enter an leave the cell
        • Cytoplasm is a jelly like substance that chemical reactions take place
    • Tissues and organs
      • Muscle and tissues contract this brings about movement
      • Glandular tissues -    produces substances such as enzymes and hormones
      • Epithelial tissue's cover most of the body
      • in plants there is xylem and phloem which transport minerals
    • Specialised cells
      • As a organism matures each cell becomes specialised
        • If a cell has many mitochondria it will need lots of energy i.e. Sperm cell

                • Neurones are specially adapted to carry signals from receptors to the CNS
                  • If a cell has a lot of ribosomes it produces many protein glands cells
              • Neurones are specially adapted to carry signals from receptors to the CNS
                • If a cell has a lot of ribosomes it produces many protein glands cells
        • Diffusion
          • The movement of particles along a concentration gradient of higher to lower
          • Examples: Diffusion of Oxygen into cells of the body through bloodstream as the cells are respiring
          • The difference between the 2 gradients is called a concentration gradient
        • Bacteria an yeast
          • Bacteria cells have a cell wall and cell membrane which surrounds the cytoplasm
          • bacteria does not have a nucleus so the genetic material is in the cytoplasm
          • Bacteria are very small and can only be seen with a microscope
          • Yeast is a single celled organism with a nucleus cytoplasm membrane and a cell wall
