(d) If both A and R are false.​

Answer 1

Answer:

(d) both A and R are false.

Explanation:

Plants, fungi and microbial cells, all produce thousands of molecules which don't have an identifiable function in the physiological processes. Example- alkaloids, flavonoids, rubber, essential oils, antibiotics, gums, resins, spices, etc.

Their extraction is not difficult or expensive and tissue culture is not needed for their commercial production.
