A complete, ready-to-teach GCSE Biology lesson exploring diffusion and the movement of substances across cell membranes. Students develop their understanding of diffusion, concentration gradients and ...
A revision poster covering Diffusion in Paper 1 of AQA Biology for both Double and Triple students. These handwritten posters have been constructed using the AQA specification, MyGCSEScience and ...
Sticky spots on cell membranes hold onto the master regulator of cell polarity, helping to ensure that the regulatory protein accumulates in high enough concentrations to trigger cell polarity. Over ...
This video explains how particles spread through diffusion from areas of high concentration to low concentration. Different factors affect the rate of diffusion – temperature, concentration gradient ...
