Root cap is derived from

Options

A. Calyptrogen
B. Pleurome
C. Periblem and histogen
D. Dermatogen

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the origin of the root cap in plants. We need to identify which of the provided options is responsible for the formation of the root cap.

2. **Analyzing the Options**:
- **Option 1: Calyptogen**: This term refers to a specific type of meristematic tissue found in the root tip of monocots. It is responsible for the formation of the root cap. Thus, this option is a strong candidate.

- **Option 2: Neuron**: Neurons are nerve cells and are not related to plant anatomy. Therefore, this option is not correct.

- **Option 3: Periblem**: The periblem is a primary meristem that primarily gives rise to the cortex and endodermis of the root. It does not contribute to the root cap, so this option is incorrect.

- **Option 4: Dermatogen**: This is a meristematic layer that gives rise to the epidermis of the root, known as the epiblema or piliferous layer. It does not form the root cap, making this option incorrect as well.

3. **Conclusion**: After analyzing all the options, it is clear that the root cap is derived from **Calyptogen**. Therefore, the correct answer is Option 1.

**Final Answer**: The root cap is derived from **Calyptogen**.
