Assertion : Secondary metabolites are produced in small quantities...
Assertion : Secondary metabolites are produced in small quantities and their extraction from the plant is difficult and expensive.
Reason: Secondary metabolites can be commercially produced by using tissue culture technique.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIfboth assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
B. Ifboth assertion and reason are true but reason is not the correct explanation of assertion.
Step-by-step solution
Secondary metabolites are biosynthetically derived from primary metabolites but more limited in distribution in plant kingdom, being restricted to a particular taxonomic group. Secondary metabolites are accumulated by plants in smaller quantities than are primary metabolites. Also, they are synthesised in specialised cell types and at distinct developmental stages, making their extraction and purification difficult and expensive. By the culture media using tissue culture techniques, secondary metabolites can be produced on a large scale.
