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