WebMay 7, 2024 · Osmosis. Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration. Water moves in or out of a cell until its concentration is the same on both sides of the plasma membrane. Semi-permeable membranes are very thin … WebNo, actually both facilitated diffusion and active transport occur. When the molecules moving from high to low conc. like Glucose is very large, then we need channel proteins to move them into the cell, and channel protein only because they have the shape and structure to do so, so that the movement is only unidirectional (into the cell).
