Cryopreservation stores seeds at ______ 10°C 0°C –20°C –196°C 2. Seed dormancy is largely regulated by the balance between ________ Abscisic acid (ABA) and Gibberellin (GA) Cytokinin and Gibberellin (GA) Auxin and cytokinin Ethylene and auxin 3. Seed priming is often used to improve germination performance. Which scenario best illustrates the mechanism of hydropriming at the cellular level? Seeds are kept completely dry but stored at a low temperature for several weeks Seeds are exposed to controlled hydration that activates metabolism without allowing radicle protrusion Seeds are coated with systemic fungicides without any water uptake Seeds are imbibed fully to the point of visible radicle emergence before drying 4. In a seed genomics study, researchers use RNA-seq to compare dry seeds and seeds 6 hours after imbibition. What is the main advantage of using transcriptomics in this context? It replaces the need for any physiological germination tests It directly measures enzyme activity in the seed without any bioinformatics It identifies which genes are actively expressed and changing during early germination It reveals permanent DNA sequence changes between the two seed stages 5. Double fertilization is best described as ________ Two pollen grains fertilizing one ovule Two fusion events occurring in the embryo sac Two eggs fertilized by two sperms Two fertilizations in the ovary 6. In angiosperms, the female gametophyte is a highly reduced, multicellular structure known as the _________ Endosperm Embryo sac Embryo Megaspore 7. The glassy state in orthodox seeds is characteristic of _____________ Aging Embryogenesis Quiescence Germination 8. The scar marking the attachment of the seed to the funiculus is ______ Hilum Raphe Micropyle Chalaza 9. The botanical term “cole crops” refers to vegetables of family _________ Brassicaceae Solanaceae Apiaceae Cucurbitaceae 10. DNA markers are used to identify ______ Phenotype Seed vigor Genotype Seed moisture Loading … Question 1 of 10 Seed Science MCQs-17
