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? 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 Randomly inserting foreign DNA into the genome without any guide RNA design 2. The embryonic root of a seed is called ____________ Hypocotyl Radicle Plumule Cotyledon 3. Seed priming enhances germination by ______ Initiating metabolic repair without radicle protrusion Increasing ABA levels Increasing dormancy Increasing storage reserves 4. Germination is considered complete when _____ Metabolism resumes Water uptake begins Radicle protrudes Leaves appear 5. Imbibition occurs even in dead seeds because _________ It depends on respiration It requires ATP It needs enzyme activation It is independent of metabolism 6. 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 Increasing seed size purely for easier mechanical planting, without biological benefits Delivering targeted biological and nutritional inputs at sowing to support early seedling vigor 7. Seed heteromorphism results in ________ Dormancy elimination Identical seeds Morphologically distinct seeds from same plant Uniform germination 8. The most critical physiological event determining successful germination is ________ ABA degradation Endosperm hydrolysis Water uptake Radicle protrusion through surrounding tissues 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. Epigenetic control of seed dormancy involves __________ All of these Histone modification Chromatin remodeling DNA methylation Loading … Question 1 of 10 Seed Science MCQs-18
