Which of the following is a correct statement regarding the plant growth ?

Options

A. Growth does not involve increase in number of parts
B. Growth occurs during definite periods
C. Well defined growing regions are absent
D. It is generally indeterminate

Answer

To determine the correct statement regarding plant growth, we can analyze each of the options provided:

### Step-by-Step Solution:

1. **Examine Option A**: "Growth does not involve increase in number of parts."
- This statement is incorrect. Growth in plants typically involves both an increase in the size of existing parts and an increase in the number of parts (e.g., leaves, branches, roots).

2. **Examine Option B**: "Growth occurs during definite periods."
- This statement is also incorrect. Plant growth is not restricted to specific periods; rather, it is continuous throughout the plant's life, although the rate of growth may vary.

3. **Examine Option C**: "Well-defined growing regions are absent."
- This statement is incorrect as well. Plants have well-defined growing regions known as meristems, which are found at the root and shoot apices. These regions are responsible for the growth of new cells and tissues.

4. **Examine Option D**: "It is generally indeterminate."
- This statement is correct. Plant growth is generally indeterminate, meaning it does not have a fixed endpoint. Plants continue to grow throughout their lifespan, producing new leaves, stems, and roots continuously.

### Conclusion:
The correct statement regarding plant growth is **Option D: It is generally indeterminate.**
