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