Question

Match List I with List II

List I & List II
Equipment & Parameter
A. IRGA & I. Transpiration rate
B. Porometer & II. Water potential
C. Osmometer & III. Photosynthetic rate
D. Pressure bomb system & IV. Osmotic potential

Choose the correct answer from the options given below:

• A. A-III, B-II, C-IV, D-I
• B. A-III, B-I, C-IV, D-II
• C. A-II, B-I, C-III, D-IV
• D. A-I, B-II, C-IV, D-III

Hint:

IRGA: photosynthetic rate.
Porometer: transpiration rate.
Osmometer: osmotic potential.
Pressure bomb: water potential.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Different equipment are used to measure different plant physiological parameters.
We need to match each equipment with its measured parameter.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the functions of each equipment.

Step 3: Detailed Explanation:
IRGA (Infrared Gas Analyser): measures photosynthetic rate (A-III).
Porometer: measures transpiration rate (B-I).
Osmometer: measures osmotic potential (C-IV).
Pressure bomb system: measures water potential (D-II).
Thus, A-III, B-I, C-IV, D-II is the correct matching.

Step 4: Final Answer:
The correct matching is A-III, B-I, C-IV, D-II.
Hence, the correct option is (B).
