The photosynthetic or assimilatory roots are observed in

Options

A. banyan
B. Vanda
C. Cuscuta
D. Tinospora

Answer

To determine which plant has photosynthetic or assimilatory roots, we can analyze the options given: Banyan tree, Wenda, Cascuta, and Tenospora.

### Step-by-Step Solution:

1. **Understanding Photosynthetic Roots**:
- Photosynthetic or assimilatory roots are specialized roots that can perform photosynthesis. They often turn green due to the presence of chlorophyll.

2. **Analyzing the Options**:
- **Banyan Tree**: This tree has prop roots or pillar roots, which are not primarily photosynthetic.
- **Wenda**: This plant has hygroscopic roots, which are adapted to absorb moisture but are not primarily photosynthetic.
- **Cascuta**: This is a total root parasite, meaning it does not perform photosynthesis as it relies on other plants for nutrients.
- **Tenospora**: This plant has adventitious roots that can turn green and perform photosynthesis, making them assimilatory roots.

3. **Identifying the Correct Answer**:
- Among the options, Tenospora is the only plant that has roots capable of photosynthesis. These roots develop from the nodes and are adapted for photosynthesis, especially during drought conditions.

4. **Conclusion**:
- Therefore, the correct answer is **Tenospora**.
