33. When water enters into a cell what happens to its OP, TP, and DPD?
(1) OP & TP increase & its DPD increase (2) OP & DPD increase & TP decrease
(3) TP & DPD decrease & OP increase (4) OP & DPD decrease & TP increase
Please find below the solution to the asked query
Osmotic pressure is the pressure required to prevent solvent from passing through a semipermeable membrane from a region of higher concentration of solute to a region of lower concentration of solute.
Turgor pressure is the pressure of the cell contents against the cell wall in plant cells. When water diffuses into the cell and cells enlarge and extension growth occurs.As water diffuses in, cytoplasm builds up a turgor pressure against the cell wall.
Diffusion pressure deficit is the pressure which opposes the diffusion of water from the region of higher chemical potential to lower chemical potential. It can be represented by a relation DPD = OP-wall pressure( turgor pressure)
Both DPD and OP oppose the entry of water and so decreases when water enters the cell. The turgor pressure will increase. Hence, option (4) is correct.
