What is an open form of growth ?

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Open Form of Growth**: The open form of growth refers to a type of growth that occurs throughout the life of a plant, specifically in dicots. This growth is characterized by the presence of secondary meristems.

2. **Distinction Between Dicots and Monocots**: It is important to note that open form of growth is primarily found in dicots, which are a group of flowering plants. In contrast, monocots do not exhibit this type of growth, as they lack the necessary secondary meristems.

3. **Role of Secondary Meristems**: Secondary meristems, also known as lateral meristems, are responsible for lateral growth, which increases the girth of the plant. This growth occurs alongside primary growth, which increases the length of the plant.
