Q. With increase in the turgidity of a cell surrounded by water the wall pressure will

AIPMTAIPMT 1997Transport in Plants

Solution:

When a cell is placed in a hypotonic solution then endosmosis occurs it means water enters in the cell and makes the cell turgid. This entry of water in the cell develops in a cell turgor pressure, which exerts pressure on the cell membrane or on the cell wall. If the cell wall is absent as is the case in animal cells then the cells burst due to turgor pressure. But in case of plant cells, wall is present to counteract the turgor pressure. This prevents the plant cells from busting in a hypotonic solution.
