OSMOSIS- WHAT IS IT AND HOW DOES IT OCCUR IN GENERAL

In the 1st option, if the medium surrounding has a higher water concentration than the cell (a very dilute solution) the cell will gain water by osmosis. Water molecules are free to pass across the ce ... to swell, the cell wall prevents it from bursting. Plant cells become 'turgid' when they are put in dilute solutions, which mean that it becomes swollen and hard. The pressure inside the cell rises, a ...
