  Nuclues

  Cell membrane

  Cytoplasm

  Mitochondria

  Nuclues

  Cell wall

  Cytoplasm

  Cell membrane

  Vacuole

  Chloroplast
• Functions of cell parts:

  Nucleus - controls the cell

  Cell surface membrane - controls what enters and leaves the cell

  Cytoplasm - Most of the cell's activities happen here

  Chloroplasts - contains chlorophyll and makes food for the plant using photosynthesis

  Vacuole - large storage space filled with cell sap

  Cell wall - supports the cell
• Unicellular - has only one cell
• Multicellular - has multiple cells
