Explanation:
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 a living cell is placed in 1% sugar solution outside the cell would be hyper-tonic relative to the inside of cell. There would be a gradient between the inside cell and outside environment. Osmosis is the movement from higher to lower concentration, therefore the cell will lose water and it would dehydrate.
