- A Genetic variability arising from random mutation occurring during tissue culture
- B Totipotency (each plant cell has the potential to develop into a whole organism)
- C Mainly vegetative reproduction occurring through stem cuttings and grafting
- D Clonal variation introduced deliberately during the subculturing process
Correct answer: B. Totipotency (each plant cell has the potential to develop into a whole organism)
Explanation: Plant tissue culture exploits totipotency: any plant cell retains the genetic information to develop into a complete plant, given the right hormones and nutrients.
Concept context
Recombinant DNA, GMOs, PCR, CRISPR, and biotechnology applications. Growing importance in NEET.
