Answer:
2.3.1 **Differentially permeable membrane** refers to a membrane that allows certain substances to pass through while restricting the passage of others based on their size, charge, or other properties.
2.3.2 In FIGURE 2, water moves from the region of higher concentration (outside the cell, in the beaker with sugar solution) to the region of lower concentration (inside the cell, in the beaker with water). This movement occurs through osmosis, driven by the concentration gradient of water molecules across the differentially permeable membrane. Water moves to dilute the higher concentration of solute (sugar) outside the cell.
2.3.3 The physiological process represented in FIGURE 2 is **osmosis**, which is the movement of solvent molecules (usually water) across a differentially permeable membrane from a region of lower solute concentration to a region of higher solute concentration. Mark me the brainliest
