Question

What will happen if we will keep plant and animal cell in sugar or salt solution?

Answer 1

If we place a cell in hyper tonic solution like in sugar solution, the cell will shrink. It is because the movement of water takes place from lower solute concentration to higher solute concentration i.e from inside cell to outside in the sugar solution to attain equilibrium. It results in the shrinkage of cell.

Answer 2

Nothing happens if it is placed in solution isotonic to the plant or animal cell.
But if the sugar or salt soln is hyper tonic wrt cell then exosmosis takes place and the plant or animal cell shrinks in size. And plasmolysis takes place.
