Choose the correct statements regarding guttation and pick the correct option from the codes given below
It occurs through specialised pore called hydathode.
Hydathodes can be located margin and tips of leaves.
It occurs in plants growing under condition of low soil moisture and high humidity.
It occurs in herbaceous plants when root pressure is low and transpiration is high.

Options

A. I and II
B. III and IV
C. I,II and IV
D. All of these

Answer

To solve the question regarding guttation, we need to evaluate each statement provided and determine which ones are correct. Here’s the step-by-step breakdown:

### Step 1: Analyze the First Statement
**Statement:** It occurs through specialized pores called hydathodes.

**Evaluation:** This statement is correct. Guttation occurs through specialized structures known as hydathodes, which are responsible for the exudation of water in liquid form.

### Step 2: Analyze the Second Statement
**Statement:** Hydathodes can be located at the margin and tips of leaves.

**Evaluation:** This statement is also correct. Hydathodes are indeed found at the margins and tips of leaves, facilitating the process of guttation.

### Step 3: Analyze the Third Statement
**Statement:** It occurs in plants growing under conditions of low soil moisture and high humidity.

**Evaluation:** This statement is incorrect. Guttation typically occurs in conditions of high soil moisture, not low. High humidity can be a factor, but low soil moisture contradicts the process of guttation.

### Step 4: Analyze the Fourth Statement
**Statement:** It occurs in herbaceous plants when root pressure is low and transpiration is high.

**Evaluation:** This statement is also incorrect. Guttation occurs when root pressure is high, and transpiration is low, particularly at night or early morning when the conditions are favorable for water exudation.

### Conclusion
Based on the evaluations:
- The correct statements are the **1st and 2nd** statements.
- The incorrect statements are the **3rd and 4th**.

### Final Answer
The correct option is the one that includes the 1st and 2nd statements.
