Mark the correct statement

Options

A. Lenticles remain always open.
B. Lenticels pores are larger than stomata
C. Lenticular transpiration is only `1%` of the total transpiration.
D. All the above.

Answer

To solve the question "Mark the correct statement" regarding lenticels, we need to evaluate each of the provided statements one by one.

### Step-by-Step Solution:

1. **Evaluate the First Statement: "Lenticels remain always open."**
- Lenticels are specialized structures found on the bark of woody plants that facilitate gas exchange. Unlike stomata, which can open and close, lenticels are considered unregulated and remain open at all times. Therefore, this statement is **correct**.

2. **Evaluate the Second Statement: "Lenticels pores are larger than stomata."**
- Lenticels have larger openings compared to stomata. Stomata are microscopic pores that regulate gas exchange and are typically much smaller than lenticels. Thus, this statement is also **correct**.

3. **Evaluate the Third Statement: "Lenticular transpiration is only 1% of the total transpiration."**
- Lenticular transpiration refers to the loss of water vapor through lenticels. It is indeed a very small fraction of the total transpiration that occurs in plants, with estimates suggesting it accounts for about 0-1% of total transpiration, which makes this statement **correct**.

4. **Evaluate the Fourth Statement: "All of the above."**
- Since all the previous statements (1, 2, and 3) have been determined to be correct, the fourth statement, which claims that all the above statements are correct, is also **correct**.

### Conclusion:
Based on the evaluation of each statement, the correct answer is **"All of the above."**
