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