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