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? Replacing the need for any field fertilization during the entire crop cycle 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 2. The embryonic root of a seed is called ____________ Radicle Plumule Hypocotyl Cotyledon 3. Germination is considered complete when _____ Water uptake begins Metabolism resumes Leaves appear Radicle protrudes 4. 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 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 Introducing multiple off-target mutations to accelerate variation, then selecting surviving plants 5. Epigenetic control of seed dormancy involves __________ DNA methylation Histone modification Chromatin remodeling All of these 6. The most critical physiological event determining successful germination is ________ Radicle protrusion through surrounding tissues Water uptake Endosperm hydrolysis ABA degradation 7. Seed priming enhances germination by ______ Increasing dormancy Increasing ABA levels Increasing storage reserves Initiating metabolic repair without radicle protrusion 8. Imbibition occurs even in dead seeds because _________ It is independent of metabolism It requires ATP It needs enzyme activation It depends on respiration 9. Seed heteromorphism results in ________ Uniform germination Identical seeds Morphologically distinct seeds from same plant Dormancy elimination 10. Dormancy release in many species involves decreasing ________ Gibberellic Acid (GA) /Abscisic Acid (ABA) ratio Auxin/cytokinin ratio Ethylene/Abscisic Acid (ABA) ratio Abscisic Acid (ABA) / Gibberellic Acid (GA) ratio Loading … Question 1 of 10 Seed Science MCQs-18
