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