Cells

  • Microscopy, size and magnification (CCEA)

    To examine cells and learn more about their structure, we need to be able to see them in very fine detail.

  • Cells and specialisation (CCEA)

    Plants and animals consist of different types of cell that work together. Animal and plant cells have certain structures in common. Many cells are specialised and are adapted for their function.

  • Diffusion (CCEA)

    Diffusion is the random movement of a substance from a region of high concentration to a region of low concentration.

Body systems

  • Osmosis and plant transport (CCEA)

    Osmosis is the diffusion of water molecules from a dilute solution (high concentration of water) to a more concentrated solution (low concentration of water) across a selectively permeable membrane.

  • The circulatory system (CCEA)

    Blood is pumped away from the heart at high pressure in arteries, and returns to the heart at low pressure in veins. The human circulatory system is a double circulatory system.

  • Reproduction, fertility and contraception (CCEA)

    Most animals carry out sexual reproduction. Sexual reproduction involves the joining of two sex cells (gametes) – the sperm (male gamete) and the egg/ovum (female gamete).
