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