11. ‘Hairy roots’ induced in vitro by the infection of Agrobacterium rhizogenes are characterized by:
(A) P and R only
(B) P and Q only
(C) Q and R only
(D) R and S only
Where:
P. a high degree of lateral branching
Q. genetic instability of culture
R. an absence of geotropism
S. poor biomass production
Answered
Answer: (A) P and R only
Explanation: ‘Hairy roots’ are known for high lateral branching and the absence of geotropism. They are genetically stable and have good biomass production, so genetic instability and poor biomass production are not characteristic features.
