Turgidity of the cell is maintained by

Assertion ($\mathrm{A}$): Pea seeds swell more on imbibition than wheat seeds.

Reason ($\mathrm{R}$): Proteins have a high imbibing capacity.

 Differentiate between the following pairs on the basis of what is indicated in the brackets.

Hypotonic solution and Hypertonic solution [condition of a plant cell when placed in them].

Assertion ($\mathrm{A}$): The flow of solvent molecules from a pure solvent to the solution through semipermeable membrane is osmosis.

Reason $\left(\mathrm{R}\right):$ Pure solvent molecules flow out of the solution through semipermeable membrane if a pressure larger than the osmotic pressure is applied to the solution side.

The correct answer is:

Choose the correct option.

Correct the following statements by changing the underlined words:

Xylem transports starch from the leaves to all parts of the plant body.

The containers $\mathrm{X}$ and $\mathrm{Y}$ have $1$ litre of pure water and $1$ litre of $0.1 \mathrm{M}$ sugar solution, respectively. Which one of the following statements would be correct regarding their water potential $\left(\mathrm{\Psi }\right)$ and osmotic potential $\left(\mathrm{\Psi }s\right)?$
