Interfascicular cambia originate from cells of -

Options

A. Medullary ray
B. Cortex
C. Endodermis
D. Fascicular cambia

Answer

To answer the question regarding the origin of interfascicular cambia, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cambium**: Cambium is a type of plant tissue that is responsible for secondary growth. It is a lateral meristem that produces secondary xylem (wood) and secondary phloem (bark).

2. **Identifying Interfascicular Cambium**: Interfascicular cambium specifically refers to the cambium that forms between the vascular bundles (fascicles) in dicotyledonous plants.

3. **Origin of Interfascicular Cambium**: The interfascicular cambium originates from the cells of the medullary rays. Medullary rays are parenchyma cells that run radially in the stem and connect the pith to the vascular bundles.

4. **Conclusion**: Therefore, the interfascicular cambium originates from the cells of medullary rays.

### Final Answer:
Interfascicular cambia originate from the cells of medullary rays.
