WebFaster diffusion = larger surface area, steeper concentration gradient, and shorter diffusion pathway. With this in mind, you can see how the alveoli are well adapted for fast diffusion/gas exchange: There are many many alveoli (around 500 million!)- meaning there is a large surface area for diffusion to occur. WebLearning Outcomes. The roots of seed plants have three major functions: anchoring the plant to the soil, absorbing water and minerals and transporting them upwards, and …
