• what does the cytoplasm do?

  where most of the chemical reactions happen
• what does the cell membrane do?

  Controls the movement of substances in and out of the cell.
• what does the mitochondria do?

  where aerobic respiration occurs- releasing energy for the cell
• what do ribosomes do?

• what extra organelles do plant and algal cells have?

  cell wall, chloroplasts and a permanent vacuole
• what does the cell wall do?

  strengthens the cell and gives it support
• what is the cell wall made out of?

  Cellulose
• what do chloroplasts do?

  contain chlorophyll which absorbs light for photosynthesis
• what is the permanent vacuole?

  a space in the cytoplasm filled with cell sap
• what does the permanent vacuole do?
