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