Osmotic pressure increases with increase in temperature.
How do root hair absorb water from soil?
By osmosis
What is turgor pressure?
Turgor pressure is the force within the cell that pushes the plasma membrane against the cell wall.
In which cells is turgor pressure not seen?
Cell wall less cells- animal cells
What happens to turgor pressure as water enters the cell?
Turgor pressure increases
What is also called pressure potential of a cell?
Turgor pressure
What is water potential mathematically equal to?
Ψ = ΨS + ΨP
What is the relation between solute potential and pressure potential of fully turgid cell?
ΨS = ΨP
What is the relation between diffusion deficit pressure, osmotic pressure and turgor pressure?
DPD=OP-TP
What is the relation between osmotic pressure and solute potential?
ΨS= -OP
What is limiting plasmolysis?
Protoplasm of plant cell shrinks after keeping in hypertonic solution.
What is incipient plasmolysis?
Vacuole starts contracting, cell is seen shrinking
How many stages does plasmolysis have?
Three stages-, Limiting plasmolysis, Incipient plasmolysis, Evident plasmolysis
What is found between cell wall and cell membrane of a plasmolysed cell?
Hypertonic solution
‘A’ has high diffusion deficit pressure and ‘B’ has low diffusion deficit pressure. Water will move from?
B to A
