Seed heteromorphism results in ________ Uniform germination Morphologically distinct seeds from same plant Dormancy elimination Identical seeds 2. 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 3. Seed priming enhances germination by ______ Initiating metabolic repair without radicle protrusion Increasing storage reserves Increasing ABA levels Increasing dormancy 4. Epigenetic control of seed dormancy involves __________ Histone modification Chromatin remodeling All of these DNA methylation 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? Avoiding any phenotypic evaluation because CRISPR changes are assumed to be predictable 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 Introducing multiple off-target mutations to accelerate variation, then selecting surviving plants 6. The embryonic root of a seed is called ____________ Radicle Hypocotyl Cotyledon Plumule 7. Imbibition occurs even in dead seeds because _________ It is independent of metabolism It needs enzyme activation It depends on respiration It requires ATP 8. The most critical physiological event determining successful germination is ________ Water uptake ABA degradation Endosperm hydrolysis Radicle protrusion through surrounding tissues 9. Germination is considered complete when _____ Leaves appear Radicle protrudes Metabolism resumes Water uptake begins 10. 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 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 Increasing seed size purely for easier mechanical planting, without biological benefits Loading … Question 1 of 10 Seed Science MCQs-18
