Answer :

Cells without cell walls may swell and burst when lots of water moves into them.
Cells without cell walls will shrivel up when lots of water moves out of them. This is because the outermost layer (the cell membrane) is very flexible.

Cells with cell walls will have their cell membranes pushed up against the cell walls if lots of water moves into the cell, this is because the cell wall is rigid so cannot stretch to accommodate the water very much.
Cells with cell walls will have their cell membrane barely touching the cell wall if lots of water moves out of the cell, as there is less pressure.
