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