1.TO INVESTIGATE OF DIFFERENT TYPE OF CELL TO THE FIXED SHAPED OF THE CELLProblem statement: Does plant cell and animal cell have fixed shape?Hypothesis: Plant cell has a fixed shape but not animal cellVariables: MV : type of cell/plant cell and animal cell RV : fixed shape of cell CV : One drop of methylene blue solution and distilled waterApparatus and materialsGlass slide,cover slips,forcep,knife,microscope,toothpick,white tile/cutting board,methylene blue solution,iodine solution,iodine solution,filter paper,distilled water,onion scale leaf,cheek cellProcedure1. A scale leaf from an onion bulb are obtained2. By using a forcep .the inner surface of onion scale leaf is peeled off3. One drop of distilled water was placed in the middle of glass slide4. With a needle ,the cover slip is dropped slowly at 450 to the glass slide so that no air bubble being trapped5. A drop of iodine solution was dropped at one side of the cover slip6. A filter paper was placed at the opposite end of the opposite end of the cover slip to allow the spreading of solution absorbing excess solution7. The slide is observed under a light microscope using a low power objective lens then high power objective lens8. The plant structure is then drawn and recorded by using a microscope 9. This experiment is repeated using a cheek cell 10. The mouth is rinsed before starting with experiment11. By using toothpick, the inner mouth were scrapped to get some cheek cell12. Then the cheek
