Plant Cells That Lack Cell Walls, Called Protoplasts, May Be

Plant cells that lack cell walls, called protoplasts, may be prepared by the incubation of plant tissues with enzymes that destroy the cell wall. Protoplasts are much more sensitive than intact plant cells to the solute concentration of the solution in which they are suspended. Why?

A) The lack of a cell wall prevents the cells from shrinking.
B) The lack of a cell wall prevents osmosis.
C) Cells that lack the cell wall cannot develop a pressure potential to counter the osmotic potential and could burst when placed in hypertonic solutions.
D) Cells that lack the cell wall cannot develop a pressure potential to counter the osmotic potential when placed in hypotonic solutions.
E) The cell wall contains aquaporins.
