What happens as a result of osmosis when an animal cell containing 1% sugar is placed in pure water
Mama L [17]

The process of osmosis is the movement of water through a selectively permeable membrane from an area of higher concentration to an area of lower concentration.

If 1% sugar solution is placed in pure water, then there would be a higher concentration of water molecules outside the cell compared to inside the cell. The solution outside the cell would be hypo-tonic (containing fewer solute molecules than inside the cell). Water will move into the cell by inward osmosis and the cell would then swell.
