2.2 Describe cell structures, including the nucleus, cytoplasm, cell membrane, cell wall, chloroplast and vacuole


Cell structures
  • Nucleus - controls the cell's behavior
  • Cytoplasm - makes up most of the cell, a gelatine-like subtance
  • Cell membrane - a thin wall that keeps the cell together
  • Cell wall - a harder, outer wall that keeps the cell's shape and stops it from bursting when it is full of water
  • Chloroplast - allows the organism to photosynthesize: to produce glucose from water and carbon dioxide
  • Vacuole - Where cell sap is stored, along with other nutrients
Key
Yellowish orange = Features in both plant and animal cells
Green = Typically associated with plant cells
Pale purple = Typically associated with plant cells, but a small temporary vacuole can be found in animal cells too
