Difficulty: Easy
Correct Answer: All of the above
Explanation:
Introduction / Context:Micropropagation is widely adopted in horticulture, forestry, and seed potato programs because it provides fast, clean, and scalable clonal production. The method is especially powerful for elite, sterile, or recalcitrant genotypes that cannot be propagated sexually.
Given Data / Assumptions:
Concept / Approach:Evaluate whether each listed benefit is a recognized strength of micropropagation. Speed (rapid multiplication), sanitation (disease-free plants), and the ability to propagate sterile hybrids are all hallmark advantages.
Step-by-Step Solution:
Confirm (a): Cytokinin-driven shoot proliferation enables rapid multiplication of elite clones.Confirm (b): Meristem culture and indexing help eliminate or avoid systemic pathogens, yielding clean stock.Confirm (c): Sterile or seedless cultivars (e.g., triploids) can be multiplied vegetatively in vitro.Therefore, the most comprehensive choice is “All of the above.”Verification / Alternative check:Commercial success stories (banana, sugarcane, ornamentals) consistently cite these advantages as the rationale for adopting tissue culture pipelines.
Why Other Options Are Wrong:
Common Pitfalls:Assuming sterility prevents clonal propagation; micropropagation bypasses sexual reproduction entirely.
Final Answer:All of the above
