This diagram covers Cell Transport โ Tap to Explore the 3 Mechanisms within Cell Transport for GCSE Biology. Diffusion, osmosis, active transport, factors affecting transport, surface area to volume ratio, and practical investigations It is section 2 of 19 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.
Practice questions for Cell Transport
Which statement best describes diffusion?
Explain how osmosis causes a plant cell to become plasmolysed when placed in a concentrated sugar solution.
Quick recall flashcards
Define diffusion
The movement of particles from an area of high concentration to an area of low concentration down a concentration gradient. No energy is required (passive process).
Define osmosis
The movement of water molecules from an area of high water concentration (low solute concentration) to an area of low water concentration (high solute concentration) through a semi-permeable membrane.
