Conifers are adapted to tolerate extreme environmental conditions because of

Options

A. Broad hardy leaves
B. Superficial atomata
C. Thick cuticle
D. Presence of vessels

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks why conifers are adapted to tolerate extreme environmental conditions. We need to evaluate the options provided to determine which one contributes to this adaptation.

2. **Evaluating the Options:**
- **Option 1: Broad Hardy Leaves**
- While broad leaves can increase the surface area for photosynthesis, they are not specifically an adaptation for extreme environments. Thus, this option is not correct.

- **Option 2: Superficial Stomata**
- Superficial stomata facilitate gas exchange (O2 and CO2), but they do not directly contribute to the tolerance of extreme conditions. Therefore, this option is also incorrect.

- **Option 3: Thick Cuticle**
- A thick cuticle is a waxy layer that prevents water loss, which is crucial for survival in extreme conditions (like drought). It also protects the mesophyll cells and vascular bundles. This option is likely the correct answer.

- **Option 4: Presence of Vessels**
- The presence of vessels primarily aids in the conduction of water and nutrients but does not specifically address the adaptation to extreme environmental conditions. Thus, this option is incorrect.

3. **Conclusion:**
After evaluating all the options, the correct answer is **Option 3: Thick Cuticle**. This adaptation helps conifers to tolerate extreme environmental conditions by preventing water loss and providing protection.
