Answer: Totipotency.
- A Senescence
- B Dormancy
- C Totipotency
- D Abscission
Correct answer: C. Totipotency
Explanation: Totipotency is the capacity of a single differentiated plant cell to divide and develop into a complete plant - the basis of tissue culture.
Geometric growth (where both daughter cells keep dividing) produces this classic S-shaped curve: a slow lag phase, a rapid exponential phase, and a levelling-off stationary phase as nutrients or space become limiting - the same fundamental pattern seen in population growth.
Concept context
Phases of plant growth, the five classical plant hormones plus newer ones, photoperiodism, vernalization, and seed dormancy.
