The form of growth wherein new cells are always being added to the plant body by the activity of the meristem is called

Answer

**Step-by-Step Solution:**

1. **Understanding Meristems**: Meristems are regions in plants where cells are actively dividing. These cells are small, metabolically active, and densely packed with organelles. They play a crucial role in plant growth.

2. **Function of Meristems**: The primary function of meristems is to produce new cells. As these cells divide, they contribute to the overall growth of the plant body.

3. **Types of Growth**: In plants, growth can occur in different forms. The growth associated with meristems is continuous, as new cells are consistently being added.

4. **Identifying the Growth Type**: The specific type of growth characterized by the continuous addition of new cells due to the activity of meristems is referred to as "open form of growth."

5. **Conclusion**: Therefore, the form of growth wherein new cells are always being added to the plant body by the activity of the meristem is called "open form of growth."

**Final Answer**: Open form of growth.
