Which is the probable value of osmotic pressure in a cell having water potential -7 atm, and no other pressure present
1 \(-3 \mathrm{~atm}\)
2 \(-7 \mathrm{~atm}\)
3 \({\rm{Zero}}\)
4 \(+7 \mathrm{~atm}\)
Explanation:
No other pressure present means no turgor pressure Water potential \(=\) solute potential + turgor pressure -7 atm \(=\) solute potential +0 Therefore solute potential \(=-7 \mathrm{~atm}\) Osmotic pressure \(=\)-solute potential Therefore, \(\mathrm{OP}=+7 \mathrm{~atm}\)

The osmotic expansion of a cell kept in water is chiefly regulated by
1 Nucleus
2 Vacuoles
3 Plastids
4 Mitochondria
Explanation:
The osmotic expansion of a cell kept in water is chiefly regulated by vacuoles. This is because, vacuoles have single membraned tonoplast and act as a semipermeable membrane, allowing selective entry and exit of water.

Numerically osmotic pressure is equivalent to
1 Osmotic potential
2 Pressure gradient
3 Water potential
4 All are correct
Explanation:
Numerically osmotic pressure is equivalent to the osmotic potential, but with an opposite sign. Osmotic pressure is positive, while osmotic potential is negative.

In the given diagram, Which cell has maximum absorbing capacity?
1 Cell B
2 Cell A
3 Cell C
4 Cell D
Explanation:
More negative value of \(\psi w\), lesser the water potential and more the absorbing capacity
