The correct Answer is:
To solve the question of matching the items from Column I to Column II, we will analyze each item in Column I and determine its corresponding function or measurement from Column II. ### Step-by-Step Solution: 1. **Identify Ganong's Potometer**: - Ganong's Potometer is an instrument used to measure the rate of transpiration in plants. It does this by measuring the amount of water absorbed by the plant. - **Match**: Ganong's Potometer → (ii) Rate of transpiration. 2. **Identify Cobalt Chloride Paper**: - Cobalt chloride paper is used to determine the moisture content. When it is dry, it appears blue, and when it is moist, it turns pink. This property allows it to be used for measuring differential transpiration. - **Match**: Cobalt chloride paper → (iii) Differential transpiration. 3. **Identify Pfeffer's Auxanometer**: - Pfeffer's Auxanometer is an instrument used to measure the rate of growth in plants, specifically by measuring the elongation of the plant axis. - **Match**: Pfeffer's Auxanometer → (i) Rate of growth. 4. **Identify Porometer**: - A Porometer is used to measure the opening and closing of stomata, which is crucial for understanding transpiration rates in plants. - **Match**: Porometer → (iv) Opening and closing of stomata. ### Final Matches: - (a) Ganong's Potometer → (ii) Rate of transpiration - (b) Cobalt chloride paper → (iii) Differential transpiration - (c) Pfeffer's Auxanometer → (i) Rate of growth - (d) Porometer → (iv) Opening and closing of stomata ### Correct Combination: - The correct combination is: - a → ii - b → iii - c → i - d → iv
