Web4. Being ventilated, in animals, to make gaseous exchange more efficient by maintaining steep concentration gradients. The Lungs –adapted to make gas exchange more efficient. The lungs are made up of alveoli. Alveoli –are tiny air sacs, which give the lungs a very large surface area with a good blood supply and short diffusion distances. WebA fish uses its gills to absorb oxygen from water. Explain how the gills of a fish. are adapted for efficient gas exchange. (6) -Mixing of air and water (at surface); -Air has higher concentration of oxygen than water; -Diffusion into water; -Plants/seaweeds near surface/in light; -Produce oxygen by photosynthesis; daughter in law alienates familyWeb28 mrt. 2024 · This allows the trees to get more nutrients and water from the air. Buttress roots are a natural adaptation for a rainforest-dense environment. This adaptation helps the plants survive in poor soil and prevent them from falling over. A single root system is too small to support a tall tree. bkkhicare

"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.

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. bkk fishing hooksWebGas 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.
