What role does cohesion play in water transport through xylem? A) Mineral ions move independently of water. B) Water molecules stick to cellulose surfaces. C) Water molecules attract each other in a continuous column. D) Air bubbles are filtered out by pits. Show Answer Correct Answer: C) Water molecules attract each other in a continuous column. 2. Water movement in cells involves not only passing along cell walls but also through the cells. A) As the cell loses water, turgor pressure falls, causing water in the cell wall to enter the vacuole and restore turgor pressure. B) Water movement is solely dependent on the cell wall structure. C) Turgor pressure increases as the cell gains water, preventing water from entering the vacuole. D) Water movement is not affected by the vacuole's state. Show Answer Correct Answer: A) As the cell loses water, turgor pressure falls, causing water in the cell wall to enter the vacuole and restore turgor pressure. 3. Read the following statements and select the correct option.Statement 1:Plasmolysis is bursting of cell membrane when a cell is kept in a hypertonic SolutionStatement 2:hypertonic solution causes endosmosis.
