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