Question

Read the following statements (A-D).
(A) Colostrum is recommended for the new born because it is rich in antigens.
(B) Chikungunya is caused by a Gram negative bacterium.
(C) Tissue culture has proved useful in obtaining virus-free plants.
(D) Beer is manufactured by distillation of fermented grape juice.
How many statements are incorrect?

• A. Two
• B. Three
• C. Four
• D. One

Answer 1

The correct option is B Three

Colostrum is the milk rich in antibodies produced by the mother during initial days of lactation.

Chikungunya is caused by virus, not by bacteria.

Beer is an alcoholic beverage produced without distillation.

Hence, statements A, B and D are incorrect.

Using tissue culture technique, a whole plant is generated from a single cell, tissue or organ. A healthy plant can be obtained from a virus infected plant by tissue culture. This is possible by meristem culture as meristems are free of virus even though the whole plant is affected by virus. This is due to the fact that virus does not survive in meristematic cells. Hence, statement c is correct.

Out of the four statements given, three are incorrect and one is correct.
