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