Mitochondrion: Site of respiration. Provides the energy for the cell to
function.
Ribosomes: Site where proteins are made (including enzymes)
Vacuole: Storage.
Cytoplasm: Watery fluid that all the cell organelles float in.
Unicellular orgasms: Made of only one cell.
Multicellular: Made up of more than one cell e.g. Humans.
