Web13 sep. 2024 · September 13, 2024 by Alexander Johnson. Gills in fish Exchange of gases in fish is very efficient because of: the large surface area of the gills. the large surface area of the blood capillaries in each gill filament. the short distance required for diffusion – the outer layer of the gill filaments and the capillary walls are just one cell ... 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. office schifko.atWeb-Surface area of body surface (for gas exchange) is insufficient for the organisms needs => evolved adaptations solve problems-Active animals with fast metabolisms need more O2 than just the body surface would provide-Have specialized gas exchange surface with ventilation system (ensuring constant conc. gradient is maintained) office schematics

"WebRoots need a supply of oxygen to make ATP by aerobic respiration for active transport. The pumping of mineral ions into root hair cells creates a higher solute concentration in the roots than in the soil.

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”).

WebRoots, stems, and leaves respire at rates much lower than are characteristic of animals.
