Both apical meristem and intercalary meristem are ______Meristems.

Options

A. primary
B. secondary
C. lateral
D. both b and c

Explanation

**Step-by-Step Solution:**

1. **Understand the Types of Meristems**: Meristems are tissues in plants that are capable of continuous division and growth. They are classified into different types based on their location and function.

2. **Identify Apical Meristem**: The apical meristem is located at the tips of roots and shoots. It is responsible for the primary growth of the plant, which results in an increase in height.

3. **Identify Intercalary Meristem**: The intercalary meristem is found at the nodes of the plant, particularly in grasses. It contributes to the growth of the plant in the middle regions, allowing for elongation and growth of internodes.

4. **Determine the Classification**: Both apical and intercalary meristems are involved in primary growth, which is the growth that increases the length of the plant.

5. **Conclude the Answer**: Since both apical meristem and intercalary meristem are responsible for primary growth, they are classified as **primary meristems**.

**Final Answer**: Both apical meristem and intercalary meristem are **primary meristems**.
