Key stage 4

Identify prokaryotic and eukaryotic cells and describe the differences between them.

Prokaryotic and Eukaryotic Cells

Describe the functions of sub-cellular structures.

Cellular structures

Identify different types of specialised cells and explain their function.

Specialised cells

Describe the differences between light and electron microscopes. Describe the different features that can be seen in images from light and electron microscopes and relate this to their magnification and resolution.

Microscopes, magnification and resolution

Define diffusion and describe the factors affecting it. Explain how diffusion is affected by surface area to volume ratio and relate this to examples of exchange over surfaces in organisms.

Diffusion and exchange surfaces

Define osmosis and explain how it affects plant and animal cells.
