Cell Specialisation and Differntiation

View mindmap
  • Cell Yourself - Cell specialisation and differentiation
    • CELL DIFFERNTIATION IS THE PROCESS IN WHICH A CELL BECOMES SPECIALISED FOR ITS JOB
      • MOST DIFFERNTIATION OCCURS AS AN ORGANISM DEVELOPS
        • IN MOST ANIMAL CELLS THE ABILITY IS LOST AT AN EARLY STAGE AS THEY BECOME SPECIALISED
          • MUSCLE CELLS - TO CONTRACT TO MOVE ORGANISMS. ADAPTIONS: CONTAIN MITOCHONDRIA TO SUPPLY WITH ENERGY
          • NERVE CELLS - TO RECIEVE NERVE IMPULSES. ADAPTIONS: LONG, CAN CONNECT TO DIFFERENT PARTS OF THE BODY
          • SPERM CELLS - TO FERTILISE WITH EGG CELLS. ADAPTIONS: TAILS TO HELP MOVE, LOTS OF MITOCHONDRIA.
        • LOTS OF PLANT CELLS DON'T LOSE THE ABILITY
          • STEM CELLS - CAN TURN INTO ANY TYPE OF CELL, CAN DIVIDE TO PRODUCE MORE, FOUND IN EARLY HUMAN EMBRYOS, ADULTS CAN BE FOUND IN BONE MARROW AND ADULT ONES CAN ONLY TURN INTO SPECIFICS LIKE RED BLOOD CELLS. CAN BE GROWN IN A LAB TO PRODUCE CLONES
          • ROOT HAIR CELLS - TO ABSORB WATER AND MINERALS. ADAPTIONS: LARGE SURFACE AREA, CLOSE TO XYLEM, LARGE VACUOLE.
