What cells and diffusion means

This skill helps you understand how cells are built and how substances move across their boundaries. You learn why cells need special parts like the membrane and chloroplast to stay alive and work properly.

What you will practise

  • Identify the parts of a plant or animal cell
  • State the function of the cell membrane
  • Explain diffusion using concentration differences
  • Match organelles with their correct roles

Before you start

You should already know the basic idea of living cells and simple plant and animal differences. It also helps if you can read short science definitions and label diagrams.

Worked example

One question from this skill's own question bank, shown with its full working.

Question

Which part controls what enters and leaves the cell?

  • nucleus
  • cell membrane
  • cytoplasm
  • vacuole
Answer: cell membrane

Working: The cell membrane controls movement in and out of the cell.

Common mistakes to avoid

  • Confusing the cell membrane with the cell wall. The membrane controls entry and exit.
  • Thinking diffusion needs energy. It is a passive movement from high to low concentration.
  • Mixing up chloroplast with other cell parts. Chloroplasts are the site of photosynthesis.
  • Using vague answers like 'it helps the cell'. Name the exact function instead.

Curriculum and exam alignment
