OP, TP, WP, DPD in Transport of Plants

OP (Osmotic Pressure):
Osmotic pressure is the pressure that develops in a solution due to the movement of water molecules across the selectively permeable membrane. In plants, osmotic pressure is responsible for the uptake of water from the soil into the roots.

TP (Turgor Pressure):
Turgor pressure is the pressure exerted by the cell contents against the cell wall due to the uptake of water. In plants, turgor pressure is responsible for maintaining the rigidity of the cells and tissues.

WP (Water Potential):
Water potential is the potential energy of water molecules in a solution. It is a measure of the tendency of water to move from one place to another. In plants, water potential is responsible for the movement of water from the roots to the leaves and other parts of the plant.

DPD (Diffusion Pressure Deficit):
Diffusion pressure deficit is the difference between the water potential of a solution and the water potential of the atmosphere. In plants, DPD is responsible for the movement of water from the roots to the leaves against the force of gravity.

Conclusion:
In summary, OP, TP, WP, and DPD are all important factors in the transport of water in plants. Osmotic pressure helps to uptake water from the soil, turgor pressure maintains the rigidity of cells and tissues, water potential helps in the movement of water from the roots to the leaves, and diffusion pressure deficit helps in the movement of water against gravity. Understanding these factors is essential for understanding the physiology of plants and how they transport water.

OP of solution is equal to pressure, which is required to be applied on a solution in order to prevent an increase in its volume due to tendency of solvent to enter in which the two are separated by a semipermeable membrane...
TP--when a cell is immersed in water, then water entersvintobthe cell bcoz OP of cell sap is higher than that of the water. The cell content press against the wall or the develop a pressure gradient against the cell wall, which is called tutor pressure...
WP--The TP is balanced by an equal but opposite pressure of the thick cell wall on the enclosed solution or protoplasm is known as Wall Pressure...
DPD---The difference btw the diffusion pressure of the solution and it's pure solvent at particular temperature is called DPD...
DPD==OP--TP or WP....
Hope it helps u out....
