Question

Match column-I with column-II. Select the option with correct combination.

Column-I		Column-II
1.	Hypertonic	p.	Two molecules move in the same direction across the membrane.
2.	Capillarity	q.	External solution is more concretrated than cell sap.
3.	Symport	r.	Water loss in the form of droplets.
4.	Guttation	s.	Ability of water to rise in thin tubes.

• A. 1-q, 2-s, 3-p, 4-r
• B. 1-q, 2-s, 3-r, 4-p
• C. 1-q, 2-r, 3-p, 4-s
• D. 1-q, 2-p, 3-s, 4-r

Answer 1

The Correct Option is A

• Hypertonic (1): A hypertonic solution is one in which the external solution is more concentrated than the cell sap, leading to water loss from the cell. This matches with q.
• Capillarity (2): Capillarity refers to the ability of water to rise in thin tubes due to surface tension and adhesion forces. This corresponds with s.
• Symport (3): Symport is a type of transport mechanism where two molecules move in the same direction across a membrane. This corresponds with p.
• Guttation (4): Guttation is the process of water loss in the form of droplets, primarily through special pores on plants. This corresponds with r.

The correct answer is (A) : 1-q, 2-s, 3-p, 4-r.

Answer 2

The correct answer is: (A) 1-q, 2-s, 3-p, 4-r.

Let's match the terms from Column-I with the correct explanations in Column-II:

• 1. Hypertonic – A hypertonic solution has a higher concentration of solutes compared to the cell sap, meaning that water will move out of the cell. The correct match is 1-q: External solution is more concentrated than cell sap.
• 2. Capillarity – Capillarity is the ability of water to rise in thin tubes due to the adhesive and cohesive forces between the water molecules and the walls of the tube. The correct match is 2-s: Ability of water to rise in thin tubes.
• 3. Symport – Symport refers to the type of transport where two molecules move in the same direction across the membrane. The correct match is 3-p: Two molecules move in the same direction across the membrane.
• 4. Guttation – Guttation is the process of water loss in the form of droplets from the tips of leaves, usually at night when transpiration is minimal. The correct match is 4-r: Water loss in the form of droplets.

Thus, the correct matching is 1-q, 2-s, 3-p, 4-r.
