Values of DPD for plant cells under hypotonic-isotonic

Question

Write down the values of DPD for the plant cells under hypotonic, isotonic and hypertonic media?

Answer 1

In plant cells under the hypertonic medium there is loss of the water for the exterior, SF > 0 (or the vacuolar pressure is elevated because it is concentrated) and TP = 0 (there is no distension of cell wall because the cellular volume is lessens) as a result DPD = SF. These cells are named as plasmolysed cells, situation typified by the retraction of cell membrane that detach from cell wall.

In plant cells the under isotonic medium there is no raise of the internal of water volume, SF > 0 and TP = 0 (because the cell wall isn’t distended). The cell membrane faintly touches the cell wall and in this circumstance the cell is named as flaccid cell.

In plant cells under the hypotonic medium there is propensity of water to come in, SF = TP (because the osmotic pressure is entirely compensated by distension of cell wall) and DPD = 0. The cell which has expanded itself to this point is named as turgid cell.
