Factors Affecting Diffusion and Impact on Organisms

The video explores diffusion, focusing on factors affecting its rate: concentration gradient, temperature, and surface area. It explains the significance of surface area to volume ratio in organisms, highlighting differences between single-celled and multicellular organisms. The video also discusses specialized exchange surfaces in animals and plants, emphasizing adaptations for effective exchange, such as large surface areas, thin membranes, and efficient blood supply.
