There are two main types of cells; animal cells and plant cells.

Every cell (both animal and plant) contains Mitochondria, Cytoplasm, a Nucleus and a Cell Membrane. However, plants also have Chloroplasts, a Vacuole and a Cell Wall (which animal cells do not have).

  • Mitochondria ~ most reactions for aerobic respiration takes place here.
  • Cytoplasm ~ most chemical reactions happen here.
  • Cell Membrane ~ controls what enters and leaves the cell, as well as holding the cell together.
  • Cell Wall ~ supports the cell.
  • Chloroplasts ~ where photosynthesis happens (contains chlorophyll)
  • Vacuole ~ contains cell sap.

A unicellular organism is a living thing that is made up of only one cell. They have adaptations that help them to survive in their environments. An example of a unicellular organism is the Amoeba, which lives in the water and has a Vacuole in order to get rid of excess water.

In order to bring you this lesson I used the CGP KS3 Knowledge Organiser.
