Green, aerial photosynthetic roots are found in

Options

A. Viscum
B. Taeniophyllum
C. Rhizophora
D. Cuscuta

Answer

To solve the question "Green, aerial photosynthetic roots are found in", we need to analyze the options provided and determine which plant has these specific root characteristics.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a plant that has green, aerial, photosynthetic roots. This means we are looking for roots that are above ground, capable of photosynthesis, and contain chlorophyll (which gives them a green color).

2. **Evaluate the Options**:
- **Viscum**: This is a genus of parasitic plants (mistletoe). They have haustorial roots that attach to host plants to extract nutrients, but they do not have photosynthetic aerial roots. Therefore, this option is incorrect.

- **Cascuta**: Also known as dodder, this is another parasitic plant. It has no chlorophyll and relies entirely on its host for nutrients. Its roots are not photosynthetic. Thus, this option is also incorrect.

- **Rhizophora**: This genus includes mangrove species. While they have specialized roots (like stilt roots and pneumatophores) that help with gas exchange, they do not have green, aerial, photosynthetic roots. Their roots are primarily for support and respiration, not photosynthesis. Therefore, this option is incorrect.

- **Tenuophilum**: This plant does have green, aerial roots that are capable of photosynthesis. The presence of chlorophyll allows these roots to perform photosynthesis, making this the correct option.

3. **Conclusion**: After evaluating all the options, we find that the correct answer is **Tenuophilum**, as it is the only plant listed that has green, aerial, photosynthetic roots.

### Final Answer:
Green, aerial photosynthetic roots are found in **Tenuophilum**.
