Monocot root has

Options

A. Vascular bundles are conjoint and open type
B. Endodermis is devoid of casparian sptrips
C. Pericycle gives rise to phellogen
D. Pith is well developed

Answer

To answer the question regarding the characteristics of monocot roots, let's break down the features one by one.

### Step-by-Step Solution:

1. **Vascular Bundles**:
- In monocot roots, the vascular bundles are indeed conjoined. However, they are not of the open type; they are classified as closed. This means that the vascular bundles do not have cambium between the xylem and phloem. Therefore, the statement that vascular bundles are conjoined and open type is incorrect.

2. **Endodermis**:
- The endodermis in monocot roots does contain Casparian strips. These strips are important for regulating the flow of water and nutrients into the vascular system. The claim that the endodermis is devoid of Casparian strips is therefore incorrect.

3. **Pericycle**:
- The pericycle in monocot roots primarily gives rise to lateral roots, not collagen. The statement that the pericycle gives rise to collagen is incorrect.

4. **Pith**:
- The pith in monocot roots is well developed and is typically larger compared to dicot roots. Therefore, the statement that the pith is well developed is correct.

### Conclusion:
Based on the analysis of the four statements, the only correct feature of monocot roots is that the pith is well developed.

### Correct Answer:
- The correct statement regarding monocot roots is: **Pith is well developed.**
