When cells are placed in hypotonic solutions, both animal and plant cells accumulate water as a result of osmosis. This causes the cells to swell. Why can plant cells better tolerate hypotonic solutions?
A. Animal cells can burst in such situations. But in plants, rigid cell walls limit how far cells can expand and exert a back pressure to limit further water uptake.
B. Plants have contractile vacuoles that continually bail out excess water that enters plant cells.
C. Sunlight causes plant cells to lose water through transpiration.
D. Stomata in plant cell leaves quickly drain excess water from the cells.
