Most animal and plant cells have the following parts:

  • Nucleus - contains DNA which is th instructions for making proteins e.g. the enzymes used in chemical rections of respiration/photosynthesis.
  • Cytoplasm - gel-like substance where proteins like enzymes are made. some enzyme-controlled reactions happen there e.g. anaerobic respiration.
  • Cell membrane - hold the cell together and controls the access in and out. allows gases and water to pass but acts as a barrier to other
