What is turgor pressure?

Pressure potential of a plant cell and its turgor pressure are

What is root pressure ?

What is vapour pressure?

Compare the statements a and b Statement a. To counteract the increase in turgor preassure in plant cells the cell wall produces an equal and opposite pressure, i.e., wall pressure Statement b.When plant cells undergo endosmosis, they swell but do not burst .

Consider the following statements 1. Xylem vessels are semi-permeable 2. Sieve tubes translocate only solutes 3. Xylem vessels do not have a turgor pressure 4. Companion cells help in maintaining pressure gradient in the sieve tubes . Which of the statements given above are correct ?

At zero turgor pressure the cell shows

The value of osmotic pressure becomes equal to turgor pressure when a cell is placed in a

If a turgid plant cell (cell with positive turgor pressure) is placed in a hypertonic solution

Two cells A and B are contiguous. Cell A has osmotic pressure 10 atm, turgor pressure-7 atm and diffusion pressure deficit 3 atm. Cell B has osmotic pressure 8 atm, turgor pressure 3 atm and diffusion pressure deficit 5 atm. The result will be
