(A)_____ In plants is largely restricted to specialized regions of active cell division, called (B)______.

Answer

To answer the question:

(A) Growth in plants is largely restricted to specialized regions of active cell division, called (B) meristems.

### Step-by-Step Solution:

1. **Identify the Concept**: The question is asking about a process in plants that is confined to specific areas where cell division occurs.
- **Hint**: Think about what processes in plants are linked to cell division.

2. **Define the Process**: The process that is largely restricted to these specialized regions is "growth". In plants, growth occurs primarily through cell division.
- **Hint**: Consider what happens when a plant grows – it involves an increase in size and number of cells.

3. **Identify the Regions**: The specialized regions where active cell division occurs are known as "meristems". These are the areas in plants that are responsible for growth.
- **Hint**: Recall the types of meristems and where they are located in the plant.

4. **Classify the Meristems**: There are different types of meristems:
- **Apical Meristems**: Located at the tips of roots and shoots, responsible for primary growth.
- **Intercalary Meristems**: Found between mature tissues, also involved in primary growth.
- **Lateral Meristems**: Responsible for secondary growth, increasing the diameter of the plant.
- **Hint**: Think about where you might find these meristems and what type of growth they facilitate.

5. **Final Answer**: Therefore, the complete answer is:
- (A) Growth in plants is largely restricted to specialized regions of active cell division, called (B) meristems.

### Summary of the Solution:
- (A) Growth
- (B) Meristems
