Question

The element which is important in determining solute concentration and oxygen evolution:

• A. Zinc
• B. Boron
• C. Nickel
• D. Chlorine

Hint:

Understanding the specific roles of elements in plant physiology can greatly enhance the effectiveness of nutrient management strategies.

Answer 1

The Correct Option is D

Step 1: Role of Chlorine in photosynthesis. Chlorine is essential for the water-splitting reaction in photosystem II, a part of the light-dependent reactions of photosynthesis. This reaction is crucial as it releases oxygen as a byproduct. 
Step 2: Impact on solute concentration. Chlorine, as a negatively charged ion (Cl-), helps in maintaining osmotic balance within the cell, influencing solute concentrations by balancing positive ions like potassium (K+) and sodium (Na+).
