Gas exchange in animals - Edexcel For an organism to function, substances must move into and out of cells. Three processes contribute to this movement – diffusion, osmosis and active transport.

Learn about and revise diffusion, osmosis and active transport with BBC Bitesize for GCSE Biology, OCR Gateway.

We consider a generic reaction–diffusion–transport system that is based on a complex model for cell polarization proposed in [6]. This model was motivated by the influence of vesicle transport along ...

Most of the urea entering Chara australis cells is rapidly metabolized to produce CO2, which diffuses out of the cells into the surrounding medium. A simple and convenient apparatus to measure both ...
