All living cells are bathed in liquid, whether they are in a single-celled organism or a multicellular one. Diffusion is effective over a specific distance and limits the size that an individual cell can attain.

WebSep 22, 2024 · Oxygen diffuses through cells at a fixed rate, so as clusters get bigger, oxygen can reach the cells in the interior only slowly if at all. Although bigger clusters had a survival advantage within this experiment, the allure of oxygen was so compelling for yeasts that they limited the size of their clusters rather than forsake it. WebIn unicellular organisms, diffusion across the cell membrane is sufficient for supplying oxygen to the cell (Figure 20.2). 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.
