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. WebHow are leaves adapted for diffusion? Surface area is increased by air spaces ( allows CO2 to come in contact with lots of cells) and thin (decrease distance carbon dioxide has …

Respiration and photosynthesis It is important to remember that plant … brain tumors that affect hearingWebSun leaves tend to be smaller than shade leaves. However, sun leaves can be up to 50% thicker than shade leaves. Sun leaves don’t need a large surface area as they don’t need to compete for sunlight. As mentioned earlier, this increased thickness is due to the additional layers of palisade mesophyll. brain tumor stage 3
