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”). WebLearn the tracheal system in insects (spiracles, trachea and tracheoles) and how these are adapted for efficient gas exchange whilst also reducing water loss... dynamic small business search sam

How does the gas exchange of air take place in plants?

WebBoth the gill filaments and lamellae provide a large surface area for gaseous exchange, increasing the efficiency of diffusion .The lamellae have many blood capillaries and a thin surface layer of cells (or epithelium), this means there is a short diffusion distance .The blood flows through the lamellae in one direction and the water flows over … WebAdaptations of leaves to maximise gas exchange: They are thin which gives a short diffusion distance. They are flat which provides a large surface area to volume ratio. … WebSpecialised exchange surfaces: 1. ↑ Surface area = more substances can be exchanged (e. villi, alveoli, root hair cells) 2. Thin layers = less diffusion distance (e. alveoli) 3. Rich blood supply = good blood flow ensures a constant steep diffusion gradient 4. Ventilation to ...

WebThe lungs are made up of tiny sacs called alveoli which presents a very large surface area for gaseous exchange. The lungs are well supplied with blood due to lots of capillaries covering the alveoli, constantly maintaining a large diffusion gradient, air is able to pass easily down this gradient due to the alveoli having very thin walls (one ... WebRoots, stems, and leaves respire at rates much lower than are characteristic of animals. Only during photosynthesis are large volumes of gases exchanged, and each leaf is well adapted to take care of its own needs. The distance that gases must diffuse in even a large plant is not great. Each living cell in the plant is located close to the surface.

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. This causes water to move from the soil into the root hair cells by …
