Question

Assimilatory (photosynthetic) roots are a characteristic of

• A. Trapa and Tinospora
• B. Taeniophyllum
• C. Both A and B
• D. None of the above

Answer 1

Answer: (C)

Both A and B

Modified adventitious roots that become green colour and perform photosynthesis are called as assimilatory roots, e.g., Taeniophyllum, Trapa, Tinospora cordifolia. Tinospora has climbing photosynthetic roots which are aerial. In Trapa, roots are underwater and called as hydrophytes. In epiphytes, like Taeniophyllum the roots are flat ribbon-like green velamen roots. Thus, the correct answer is option C.
