Dormancy release in many species involves decreasing ________ Ethylene/Abscisic Acid (ABA) ratio Gibberellic Acid (GA) /Abscisic Acid (ABA) ratio Abscisic Acid (ABA) / Gibberellic Acid (GA) ratio Auxin/cytokinin ratio 2. Imbibition occurs even in dead seeds because _________ It needs enzyme activation It requires ATP It depends on respiration It is independent of metabolism 3. A technologist designs a film coating for vegetable seeds that includes beneficial microbes and micronutrients. Which outcome most directly reflects the purpose of such an advanced seed coating? Increasing seed size purely for easier mechanical planting, without biological benefits Replacing the need for any field fertilization during the entire crop cycle Ensuring that seeds can germinate without any soil moisture or contact Delivering targeted biological and nutritional inputs at sowing to support early seedling vigor 4. Epigenetic control of seed dormancy involves __________ Chromatin remodeling DNA methylation All of these Histone modification 5. A seed company wants to use CRISPR-based genome editing to develop herbicide-tolerant crops. Which approach best reflects responsible and modern use of CRISPR in seed science? Randomly inserting foreign DNA into the genome without any guide RNA design Avoiding any phenotypic evaluation because CRISPR changes are assumed to be predictable Introducing multiple off-target mutations to accelerate variation, then selecting surviving plants Precisely editing a known gene associated with herbicide tolerance while screening for off-target effects 6. Seed priming enhances germination by ______ Increasing ABA levels Increasing dormancy Increasing storage reserves Initiating metabolic repair without radicle protrusion 7. Seed heteromorphism results in ________ Identical seeds Morphologically distinct seeds from same plant Uniform germination Dormancy elimination 8. Germination is considered complete when _____ Leaves appear Metabolism resumes Radicle protrudes Water uptake begins 9. The most critical physiological event determining successful germination is ________ Radicle protrusion through surrounding tissues Water uptake ABA degradation Endosperm hydrolysis 10. The embryonic root of a seed is called ____________ Hypocotyl Cotyledon Plumule Radicle Loading … Question 1 of 10 Seed Science MCQs-18
