How are roots adapted for diffusion
Web-There are a large number of alveoli, increasing the surface area available for gas exchange. The alveoli have many infoldings, further increasing the surface area.- The walls of the alveoli are thin, they are one cell thick.This reduces the diffusion distance for gases, increasing the rate of gas exchange.- The alveoli are surrounded by a dense capillary … WebDiffusion is an efficient exchange mechanism for Chlamydomonas Tracheal System of an Insect All insects possess a rigid exoskeleton with a waxy coating that is impermeable to gases Insects have evolved a breathing system that delivers oxygen directly to all the organs and tissues of their bodies

Therefore they have a large surface area to increase the rate of water absorption. Root hair cells also have a large amount of mitochondria which provide more energy for the active transport of mineral ions. These two specialisations allow for more efficient uptake.
