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