Question

Find out the pairs, which are correctly matched.

A. Cyanobacteria (i.) Biopesticides

B. Mycorrhiza (ii.) Solubilization of phosphate

C. Bacillus thuringiensis (iii.) Cry protein

D. Single-cell protein (iv.) Rhizobia

• A. A and ii.
• B. C and iii
• C. C and iv
• D. A and iii
• E. B and i

Answer 1

The correct option is B C and iii

Bacillus thuringiensis (Bt) is commonly used as a biopesticide. It is sporulating, a gram-positive facultative-aerobic soil bacterium. It synthesizes the proteins known as delta endotoxins or cry proteins which infect the insects by paralyzing the digestive tract and makes it porous.

So, the correct answer is option B.
