Abscisic acid stimulates seed germination.arrow_forwardTobacco plants invest a lot of resources into the production of secondary compounds know as alkaloids (e.g., nicotine) that we believe act as defenses against herbivores. The researchers did an experiment where they added a hormone that reduces the production of alkaloids. In graph (a), the data show that the hormone reduced the proportion of alkaloids as a function of leaf mass relative to controls- so the hormone worked. They also measured the lifetime seed production of the plants in both treatments without any herbivores present (b). They had the following results. What might you conclude/hypothesize/investigate based on the data in graph (b) (a) Chemical defenses (percent of leaf mass) 1.8% 1.4 1.0 0.6 0.2 No hormone added Hormone added (b) Lifetime seed mass (g/plant) -18 14 10 No hormone added Hormone added It would be good to test whether the hormone is very specific or whether it might also cause changes in other metabolic processes The hormone has no effect on the lifetime…arrow_forwardWhich of the following is an advantage of asexual reproduction? a. Cuttings taken from an adult plant show increased resistance to diseases. b. Grafted plants can more successfully endure drought. c. When cuttings or buds are taken from an adult plant or plant parts, the resulting plant will grow into an adult faster than a seedling. d. Asexual reproduction takes advantage of a more diverse gene pool.arrow_forward

Seed germination is solely mediated by water during episodes of heavy rain. d. Pollen grains, with walls containing sporopollenin, deter herbivores.
