WebSep 24, 2024 · Respiration occurs as dissolved oxygen in the water diffuses across the cell membrane. In turn, carbon dioxide is eliminated from the amoeba by diffusion across the membrane into the surrounding water. Water is also able to cross the amoeba plasma membrane by osmosis. WebIn unicellular organisms, diffusion across the cell membrane is sufficient for supplying oxygen to the cell (). Diffusion is a slow, passive transport process. In order for diffusion to be a feasible means of providing oxygen to the cell, the rate of oxygen uptake must match the rate of diffusion across the membrane.
