• what is the function of the nucleus?

  to control the activities of the cell and contains the genetic material
• what is the function of the cytoplasm?

  where chemical reactions take place
• what is the function of the cell membrane?

  controls the passage of substances into and out of the cell
• what is the function of mitochondria?

  where aerobic respiration takes place
