The photosynthetic or assimilatory roots are observed in

Options

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

Answer

To answer the question regarding which plant has photosynthetic or assimilatory roots, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Photosynthetic or Assimilatory Roots**:
- These are modified adventitious roots that can perform photosynthesis due to their green color. They are capable of synthesizing food for the plant.

2. **Analyzing the Options**:
- **Banyan**: This plant has prop roots that provide mechanical support, but they do not primarily function as photosynthetic roots.
- **Wanda (Orchids)**: These are epiphytic plants with roots that hang freely in the air to absorb moisture. They do not perform photosynthesis through their roots.
- **Cascuda**: This is a parasitic plant with hostorial roots that penetrate into host plants to extract nutrients. These roots do not perform photosynthesis.
- **Pterospora**: This plant has long, slender, hanging aerial adventitious roots that are green in color, allowing them to perform photosynthesis.

3. **Identifying the Correct Option**:
- Based on the analysis, the only plant that has photosynthetic or assimilatory roots is **Pterospora**.

### Final Answer:
The photosynthetic or assimilatory roots are observed in **Pterospora**.
