Question

Which of the following pairs is incorrectly matched?

• A. Yeast – amitosis division
• B. Phytophthora – cellulosic cell wall
• C. Penicillium – produce antibiotic
• D. Frankia – show association with legume

Answer 1

The correct option is D Frankia – show association with legume

Frankia belongs to the family Frankiaceae that fix nitrogen, both under symbiotic and free-living aerobic conditions. It forms root nodules but in actinorhizal and non-leguminous plants, to aid in symbiotic nitrogen fixation. It possesses nitrogenase enzyme in hyphae which is maintained in an environment with low oxygen tension. In legumes/ leguminous plants, Rhizobium forms root nodules.
Yeasts undergo amitotic division.
Phytophthora is a genus of plant damaging oomycetes. It contains cell wall mainly composed of cellulose.
Penicillium belongs to the phylum ascomycetes and produces antibiotic penicillin that inhibits growth of certain bacteria.
Hence, option d is the incorrect match.
