Transport in Cells: Transport in Cells 🧬 GCSE Biology Learning & Revision
Description
In this episode, we look at transportation in cells. We will explain how substances move into and out of cells, highlighting three key mechanisms.
Diffusion is described as the movement of particles from high to low concentration areas.
Osmosis is presented as a specific type of diffusion focusing on the movement of water across a semipermeable membrane.
Finally, active transport is characterized by the movement of particles against their concentration gradient, requiring energy.
The episode further clarifies the difference between diffusion and osmosis using the example of diluting blackcurrant squash in water.
