Consider expressing the cellular components that differ in the absence and presence of auxin.In plant physiology, What is leaf abscission and how is it controlled by the interaction between auxin and ethylene?• On a commercial scale, enhancing the level of _______ (hormone) can help to speed up fruit ripening. • What measure do fruit producers take to slow down fruit ripening that is caused by natural ethylene?• What is a ‘triple response’. Which plant hormone initiates a triple response? • A change in the ratio of ethylene to auxin controls abscission. In the autumn, the amount of __________ decreases, rendering the cells of the abscission layer more sensitive to __________.
- Which of these is caused by the effects of auxin? (choose all that apply) 1.Maintaining apical dominance 2.suppressing lateral bud growth 3. stimulating root growth in stem leaf buds 4.stimulating root elongation 5. preventing seed germination 6.phototropismWrite the structure, biosynthesis, transport and functions of auxin plant hormone?1.

- Can you answer this question, all of the parts please. A. Please explain the phenomenon of apical dominance in plant growth. B. Which plant hormone(s) involved in apical dominance?The summer is not optimal for grape growing and you're searching in your memory for something regarding plant hormones. Explain 2 ways you could utilize plant hormones (choose from auxin, ethylene, cytokinin, gibberellin, abscisic acid, salicylic acid, jasonic acid) to compensate for a problem during growing. For each way:Examples of plant hormones includea. cyclic AMP, IP3, and calcium ions.b. calcium, CDPKs, and DELLA proteins.c. auxin, cytokinin, and gibberellin.d. cryptochrome, phototropin, and phytochrome.e. statoliths, pulvini, and aerenchyma.
- Some plant hormones oppose the effect of each other. Auxins and cytokinins for example. Whereas auxins prevent shoots from branching, cytokinins promote the development of branches. What other hormones also exhibit such opposing effects? Explain your answer briefly.Match the hormone with the observation. ___ ethylene a. Your cabbage plants form ___ cytokinin elongated flowering stalks. ___ auxin b. The potted plant in your room ___ gibberellin is leaning toward the window. ___ ABA c. The last of your apples is getting ___ nitric oxide really mushy. d. The seeds of your roommate’s marijuana plant do not germinate no matter what he does to them. e. Lateral buds are sprouting. f.
