Which of the major plant hormones is adiffusible gas?a. auxin b. gibberellin c. cytokinin d. ethylene e. abscisic acidThis class of plant hormones are exuded by the plant roots. On the one hand, these plant hormones stimulate fungal metabolism and branching. On the other hand, they also trigger seed germination of parasitic plants. O A. Auxin B. Gibberellins O C. Strigolactone D. Abscisic acid O E. EthyleneIdentify the wrong match a.Senescence —Both auxin and ABA promote it b.Apical dominance — Auxin induces and Cytokinin counteracts c.Dormancy — Both ethylene and GA break it d.Callus differentiation — Auxin and cytokinins

Gaseous hormoneAn unripe avocado placed in a paper bag with an apple will ripen; its skin will turn darker green, it will soften, and it will produce an increasing amount of odors. Which plant hormone released by the apple causes this effect? Select one: a. Abscisic acid b. Auxins c. Ethylene d. Gibberellins e. Jasmonic acid
- Last Valentine's day, an 18-year old girl received a bouquet of flowers from the boy that she likes. She wanted to keep the cut flowers for a few more days so she asked for your advice on how she can retain the freshness of the flowers. Given this situation, what specific plant hormone would you recommend to her? a. abscisic acid b. auxin c. ethylene d. gibberellin e. cytokininThe apical bud of a plant produces which inhibits lateral bud growth through the process known as apical dominances. Select one: O a. Auxin O b. Cytokinin O c. Ethylene O d. Gibberellin O e. Abscisic AcidThe 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:
- 1, Choose, Which part of the plant is not included in the shoot systems of plants? a, stem b, leaves c, fruit d, roots 2, Choose, Which of the following is not a plant hormone? a, amylase b, auxins c, gibberellins d, cytokininsties of the brain and spinal cord B. Match the hormones that are supposed to be added to a plant in order to achieve the following results: a. Auxin b. Gibberellin c. Cytokinin d. Abscisic Acid e. Ethylene 19. unpollinated flowers are treated with this hormone so ovary enlarges and becomes a seedless fruit 20. substitute for temperature or light cues in plant seeds to get them to germinate 21. black spots on banana skin are spots where these are produced inducing ripening 22. seeds/bulbs stay dormant during winter to ensure survival of the plant when it germinates 23. most grape growers spray this in vines to increase length of branches between fruit clusters for more air spaces among fruits to lower fungal infections 24. sprayed on cut leaves and stems so they will remain green longer while unsprayed leaves will tum yellow and dieWhat are the effects brought by cytokinin in plants? Explain the partnerships between cytokinin with auxin and hormone mentioned in Question 3 a). (i) (ii) Write an account on interactions between gibberellins, indole acetic acid and abscisic acid in plant growth promotion and seed germination.
