Read the following three statements (A-C) and select the option which includes all the correct ones only:
i. During the primary growth of the plant, specific regions of the apical meristem produce dermal tissue, ground tissue and vascular tissue.
ii. In plants, growth is restricted to specialized regions of active cell division
iii. Secondary meristems are also known as cylindrical meristems.

Options

A. Statement (i) and (ii)
B. Statement (ii) and (iii)
C. Statement (i), (ii) and (iii)
D. Statement (i) and (iii)

Answer

To solve the question, we need to evaluate each of the three statements (A-C) regarding plant growth and meristematic tissues. Let's analyze them step by step:

### Step 1: Analyze Statement I
**Statement I**: During the primary growth of the plant, specific regions of the apical meristem produce dermal tissue, ground tissue, and vascular tissue.

- **Explanation**: During primary growth, the apical meristem is responsible for the formation of new tissues. It gives rise to three primary meristematic tissues:
- **Protoderm**: Forms the dermal tissue (epidermis).
- **Ground Meristem**: Forms the ground tissue (cortex, pith).
- **Procambium**: Forms the vascular tissue (xylem and phloem).

Thus, this statement is **correct**.

### Step 2: Analyze Statement II
**Statement II**: In plants, growth is restricted to specialized regions of active cell division.

- **Explanation**: This statement is true because plant growth occurs in specific regions known as meristems. These regions are characterized by active cell division, which allows for growth in length (primary growth) and girth (secondary growth). The primary meristematic regions include the tips of roots and shoots.

Thus, this statement is **correct**.

### Step 3: Analyze Statement III
**Statement III**: Secondary meristems are also known as cylindrical meristems.

- **Explanation**: Secondary meristems, such as the vascular cambium and cork cambium, contribute to secondary growth (increase in thickness). They are often referred to as cylindrical meristems because they form a cylinder around the stem and roots, allowing for the production of secondary xylem (wood) and secondary phloem.

Thus, this statement is **correct**.

### Conclusion
Since all three statements (I, II, and III) are correct, the correct option is the one that includes all three statements.

### Final Answer
The option that includes all the correct statements (1, 2, and 3) is **C**.
