Consider the following statements reagarding the root system of angiosperms
I. In monocots, the Fibrous root system arises from base of stem. II Region of elongation is called root hair zone . III In sweet potato, adventitious roots get swollen and store food IV. Stem of Maize and Sugaracane have supporting roots called prop roots

Options

A. I and II correct, III and IV wrong
B. II and III correct, I and IV wrong
C. II and IV correct, I and III wrong
D. I and III correct, II and IV wrong

Answer

To analyze the statements regarding the root system of angiosperms, we will evaluate each statement one by one.

### Step-by-Step Solution:

1. **Statement I**: "In monocots, the fibrous root system arises from the base of the stem."
- **Evaluation**: This statement is **true**. In monocots, the primary root is typically short-lived, and the fibrous roots arise from the base of the stem, creating a dense network of roots.

2. **Statement II**: "Region of elongation is called root hair zone."
- **Evaluation**: This statement is **false**. The region of elongation is not referred to as the root hair zone. The root hair zone is actually the maturation zone, where root hairs develop to absorb water and nutrients.

3. **Statement III**: "In sweet potato, adventitious roots get swollen and store food."
- **Evaluation**: This statement is **true**. Sweet potatoes have adventitious roots that swell and serve as storage organs for food, particularly starch.

4. **Statement IV**: "Stem of Maize and Sugarcane have supporting roots called prop roots."
- **Evaluation**: This statement is **false**. The supporting roots of maize and sugarcane are known as **tilt roots**, not prop roots. Prop roots are typically associated with plants like banyan trees.

### Conclusion:
- **Correct Statements**: I and III
- **Incorrect Statements**: II and IV

Thus, the correct answer is that statements I and III are true, while II and IV are false.
