Question

Cellulose digesting symbiont zooflagellate is

• A. Lophomonas blattarum and Trichonympha campanula
• B. Trichonympha campanula and Trichomonas hominis
• C. Leishmania tropica and Trypanosoma cruzi
• D. Trypanosoma cruzi and Lophomonas blattarum

Answer 1

The correct option is A Lophomonas blattarum and Trichonympha campanula

Trichonympha and Lophomonas is a cellulose-digesting insect-gut zooflagellate. It uses flagella for locomotion. This zooflagellate occurs as a symbiont in the intestine of termite. It secretes cellulose digesting enzyme which converts cellulose to glucose. The digested food is shared by the zooflagellates and termite. With these, the termite starve and die.

So, option A is the correct option.
