The figure given below is a diagrammatic representation of a part of the cross-section of the root in the root hair zone. Study the same and then answer the questions that follow:

Draw a well-labelled diagram of the root hair cell as it would appear if an excess of fertilizer is added to the soil close to it.

 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].

Correct the following statements by changing the underlined words:

The cell sap of root hair is Hypotonic.

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

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

Glucose is the prime source of energy in our body. However it is stored in the form of glycogen in the muscle and liver of animals and in the form of starch in plants. As a result, every time a cell requires glucose, it must hydrolyze glycogen which is an energy-consuming process. Why does the cell store glycogen instead of glucose in free form?

Give biological explanations for the following:

Plants growing in fertilized soil are often found to wilt if the soil is not adequately watered

Correct the following statements by changing the underlined words:

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

Differentiate between the following pairs on the basis of what is mentioned in the brackets:

Osmosis and Active Transport (Substances undergoing movement)
