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