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