WebThe phospholipids of plasma membranes are amphipathic: they have both hydrophilic (water-loving) and hydrophobic (water-fearing) regions. The hydrophobic core of the plasma membrane helps some materials move through the membrane, while it blocks the movement of others. Image modified from OpenStax Biology. WebDec 5, 2024 · Because the cell has a lower concentration of solutes, the water will leave the cell. In effect, the solute is drawing the water out of the cell. This may cause an animal …

WebFeb 27, 2024 · Bulk flow across capillary walls is an active process that is driven by the hydrostatic pressure of the blood in the capillaries. This pressure forces the plasma and its dissolved substances, including small molecules, through the walls. This process is important for the movement of fluids and nutrients into the tissues from the blood. WebOsmosis is much like simple diffusion but it specifically describes the movement of water (not the solute) across a selectively permeable membrane until there is an equal concentration of water and solute on both sides of the membrane. Simple diffusion and osmosis are both forms of passive transport and require none of the cell's ATP energy .
