Phtosynthetic roots are reported from

Options

A. Jussiaea
B. Rhizophora
C. Bryophyllum
D. Tinospora.

Answer

**Step-by-Step Solution:**

1. **Understanding Photosynthetic Roots:**
- Photosynthetic roots, also known as assimilatory roots, are specialized roots that can perform photosynthesis. They contain chlorophyll and can manufacture food in the presence of sunlight.

2. **Analyzing the Options:**
- The question provides four options: Jussia, Rhizophora, Bryophyllum, and Tynospora. We need to identify which of these has photosynthetic roots.

3. **Evaluating Each Option:**
- **Jussia:** This plant is known for its floating roots, but these roots do not perform photosynthesis. Therefore, this option is incorrect.
- **Rhizophora:** This plant has stilt roots and pneumatophores, which are adaptations for its aquatic habitat, but they do not have photosynthetic capabilities. Thus, this option is also incorrect.
- **Bryophyllum:** This plant does not possess photosynthetic roots. Instead, it has other adaptations for survival. Hence, this option is incorrect as well.
- **Tynospora:** This plant is known for its green, thread-like roots that can perform photosynthesis by assimilating carbon dioxide in the presence of sunlight. Therefore, this is the correct option.

4. **Conclusion:**
- After evaluating all the options, the correct answer is Tynospora, as it has photosynthetic roots.

**Final Answer:**
- Photosynthetic roots are reported from Tynospora.
