How are roots adapted for gas exchange gcse

WebGCSE gas exchange and transport (Plants + Animals) The leaf is adapted for gas exchange because it is exceedingly thin allowing gases to diffuse through the leaf very quickly. The guard cells also allow gases in and out of the leaf allowing CO₂ in and O₂ out. The leaf also contains air spaces for the gases to diffuse through. WebTake in oxygen and expel carbon dioxide directly through their skin = gas exchange surface. Oxygen diffuses through the earthworm's body surface by dissolving in the moisture on the surface and diffuses inward to the network of capillaries just under the surface. too large for diffusion through body alone. body adaption.
