Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of instruments used in plant physiology.
Step 2: Detailed Explanation:
A pressure chamber (also called pressure bomb) is used to measure water potential of plant tissues.
It measures the negative pressure (tension) in the xylem.
It is commonly used to measure leaf water potential.
Hygrometer (A): Measures relative humidity.
Porometer (B): Measures stomatal conductance.
Infra-red gas analyzer (D): Measures CO2 and H2O exchange.
Thus, the pressure chamber is used for water potential measurement.
Step 3: Final Answer:
Thus, the pressure chamber is used to measure water potential, which corresponds to option (C).
