Final answer:
The false statement about osmosis is that water crosses to the side of the membrane with a lower solute concentration. In fact, water moves to the side with higher solute concentration during osmosis.
Step-by-step explanation:
The correct answer to the question 'Which of the following statements concerning osmosis is FALSE?' is (c) 'During osmosis, water crosses to the side of the membrane with a lower solute concentration.' This statement is false because, in osmosis, water moves across a selectively permeable membrane from a region of higher water concentration to a region of lower water concentration, which corresponds to the side with higher solute concentration. Other statements are true: (a) Crenation occurs when blood cells are in a hypertonic solution, losing water and shrinking. (b) Cells in a hypotonic solution will indeed gain water, potentially leading to bursting (hemolysis). (d) Osmosis requires a selectively permeable membrane to allow the passage of water but not solutes.
