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.

What adaptations do single-celled organisms have for effective exchange with their environment?

How do multicellular organisms meet the needs of their cells for exchange?

What features do exchange surfaces in animals have to facilitate diffusion?
