Cell biology

Part of Combined Science

  • Cell biology

    • Cell structure - AQA

      Organisms are made up of cells. Most organisms are multicellular and have cells that are specialised to do a particular job. Microscopes are needed to study cells in detail.

    • Cell division - AQA

      Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information.

    • Mitosis: interactive activity - AQA

      Understand the steps of mitosis with this interactive activity from Bitesize made to the GCSE AQA Trilogy Combined Science specification.

    • Transport in cells - AQA

      For an organism to function, substances must move into and out of cells. Three processes contribute to this movement - diffusion, osmosis and active transport.

    • Sample exam questions - cell biology - AQA

      Understanding how to approach exam questions helps to boost exam performance. Question types will include multiple choice, structured, mathematical and practical questions.
