The filament of spirogyra were put into equal volumes of sugar solutions X and Y. After 5 minutes, filaments from solution X had their cells contents rounded up while those from Y were unaffected. The experiment shows that
solution X was stronger than Y
solution Y was stronger than X
Spirogyra used up the sugar in solution X
solution X is good for stimulating sexual reproduction in Spirogyra
solution Y was less contaminated than X
Correct answer is B
- osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.
