Question

Which one of the following pairs is correctly matched.

• A. Rhizobium- Parasite in the roots of leguminous plants
• B. Mycorrhizae- Mineral uptake from soil
• C. Yeast- Production of biogas
• D. Myxomycetes- The disease ring worm

Answer 1

The correct option is B Mycorrhizae- Mineral uptake from soil

A mycorrhiza is a symbiotic association composed of a fungus and roots of a vascular plant. It helps in mineral uptake from soil.

Rhizobia are soil bacteria that fix nitrogen (diazotrophs) after becoming established inside root nodules of legumes of certain plants.

Yeast, the most common one being Saccharomyces cerevisiae is used in baking as a leavening agent, where it converts the food/fermentable sugars present in dough into the gas carbon dioxide. This causes the dough to expand or rise as gas forms pockets or bubbles.

Myxomycetes from the phylum of fungus-like organisms within the kingdom Protista, commonly known as true slime molds. They exhibit characteristics of both protozoans (one-celled microorganisms) and fungi.

Thus, the correct answer is option B.
