Select the correct statement w.r.t given statements

Options

A. Water stomata is related with transpiration and guttation is related with stomata
B. Transpiration is passive process but opening of stomata is active
C. `C_(3)` plants are twice efficient in photosynthesis as compared to `C_(4)` plants whereas `C_(3)` plants are less efficient w.r.t transpiration than `C_(4)` plants
D. Minerals uptake is passive whereas water absorption is active

Answer

To solve the question, we need to analyze the statements provided and identify which one is correct. Here’s a step-by-step breakdown:

### Step 1: Understand the Concepts
- **Transpiration**: This is the process of water vapor loss from the plant through stomata. It is a passive process driven by the water potential gradient.
- **Guttation**: This is the exudation of water droplets from the leaves of some plants, usually occurring at night when the stomata are closed. It is associated with hydathodes, not stomata.
- **C3 and C4 Plants**: C3 plants undergo photorespiration, which is less efficient than the photosynthetic processes in C4 plants. C4 plants have adaptations that reduce photorespiration.

### Step 2: Analyze Each Statement
- **Option 1**: Claims that water stomata are related to transpiration and guttation is related to stomata. This is incorrect because guttation is associated with hydathodes, not stomata.
- **Option 2**: States that C3 plants are less efficient in photosynthesis compared to C4 plants due to photorespiration. This is correct since C4 plants have adaptations that minimize photorespiration.

### Step 3: Conclusion
Based on the analysis, the correct statement is from **Option 2**, which accurately describes the efficiency of C3 and C4 plants in photosynthesis.

### Final Answer
The correct statement is from **Option 2**: C3 plants are less efficient in photosynthesis compared to C4 plants due to the occurrence of photorespiration.
