How has roots adapted for gas exchange

WebGas exchange is achieved by diffusion. This is a process by which particles move naturally from a region where they are in high concentration to a region where they are in lower concentration. They move down a concentration gradient: the steeper the gradient, the faster the rate of diffusion. Web18 jul. 2024 · How do roots adapted for gas exchange? Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.

WebDiffusion. Diffusion is when particles spread from an area of high concentration to an area of low concentration. The molecules would move randomly, and they would eventually become evenly distributed. The particles move down the “concentration gradient” and this process takes no energy (it’s a “passive” process”).
