Cells: the Building Blocks of Life

Every living thing is made of cells. Tap a labelled part to find out what it does, and switch between an animal and a plant cell to spot the differences.

Tap any labelled part of the cell.

Each part of the cell has its own job to keep the cell alive and working.

Animal and plant cells

Both animal and plant cells have a nucleus, cytoplasm, a cell membrane and mitochondria. Plant cells have three extra parts: a tough cell wall, green chloroplasts for photosynthesis, and a large permanent vacuole of sap. Those extras are the giveaway that a cell is from a plant.

Check yourself

Name three parts a plant cell has that an animal cell does not.
A cell wall, chloroplasts and a large permanent vacuole. These let a plant cell keep its shape, make food by photosynthesis and store sap.
What is the job of the nucleus?
It controls the cell and contains the genetic material (DNA), which carries the instructions for everything the cell does.
Where in the cell is most energy released by respiration?
In the mitochondria. These are the tiny structures where respiration transfers energy for the cell to use.
