Quizplus · Accepted Answer

Blue light initiates germination by stimulating the production of gibberellins in the lettuce seeds. Gibberellins promote stem elongation and cell division, which are necessary for the growth of the embryo within the seed. Therefore, choice A is the best answer. Ethylene and abscisic acid are involved in the regulation of seed dormancy, which is not the case in this scenario, while cytokinins and brassinosteroids play a minor role in seed germination.
