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; 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”).

Explain how the lungs are adapted for gaseous exchange.

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 … phono pp400

How Do Buttress Roots Adapt To The Rainforest - Justagric

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. WebThe structure of a leaf. Plant leaves are adapted for photosynthesis, and the exchange of gases required for the process. The structure of the tissues is related to their functions in … Web15 mrt. 2024 · Plant leaves are adapted for photosynthesis and gas exchange.
