- The hormone that helps plants respond to drought is (A) auxin. (B) abscisic acid. (C) cytokinin. (D) ethylene.What 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.. Charles and Francis Darwin discovered that(A) auxin is responsible for phototropic curvature.(B) red light is most effective in shoot phototropism.(C) light destroys auxin.(D) light is perceived by the tips of coleoptiles.
- Phenolics, spines, terpenes, cutins, defense related proteins and suberin are some examples of plant defense. Plants are evolving to put up a fight against plant pathogen invasion. (i) Classify them into TWO (2) main classes of plant defense. (ii) What are the roles of terpenes in plant defense?Plant cells communicate in a variety of ways to elicit cellular responses. In the figure below the plant is responding the presence of light with the release of auxin. Auxin was first discovered for its ability to promote growth in plants. It is a plant hormone that inhibits the lengthening and stimulate the formation of lateral roots and root hairs. (b) Explain the role that auxin has in eliciting the plant’s response.Please answer the following parts: (a) Explain what Florigen is. (b) Explain how the floral stimulus, which originates in the minor veins of source leaves, has its effect in the shoot apical meristem. (c) Describe a classic experiment that demonstrated the existence of Florigen.
- It was observed during the early 20th century that the abscission zone of leaves of tree growing close to gas burning street lamps weakened (entered the abscission phase) earlier than trees located further away from the lamps. Experiments showed that weakening of the abscission zone was not caused by either the lamp's light or heat. Instead the research on this phenomenon led to the discovery of a new gaseous plant hormone. What is this hormone? Ethylene Abscisic acid (ABA) Gibberellins Auxin Strigolactone CytokininWhich of the following hormones are NOT matched with the proper function? abscisic acid- promotes leaf abscission cytokinins-stimulates cell division ethylene- promotes fruit ripening gibberellic acid- promotes stem elongation auxin-promotes increases in cell sizePlant cells communicate in a variety of ways to elicit cellular responses. In the figure below the plant is responding the presence of light with the release of auxin. Auxin was first discovered for its ability to promote growth in plants. It is a plant hormone that inhibits the lengthening and stimulate the formation of lateral roots and root hairs. a) Describe the plant’s response to the presence of light. (refer to picture)
- Which signaling molecule triggers the release of volatile substances that attract parasitic wasps to plant-eating caterpillars?(a) phytochrome (b) jasmonic acid (c) auxin (d) methyl salicylate (e)gibberellinThe 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:2. Plant cells communicate in a variety of ways to elicit cellular responses. In the figure below the plant is responding the presence of light with the release of auxin. Auxin was first discovered for its ability to promote growth in plants. It is a plant hormone that inhibits the lengthening and stimulate the formation of lateral roots and root hairs. (a) Describe the plant's response to the presence of light. (b) Explain the role that auxin has in eliciting the plant's response. (c) Explain how the behavioral responses of the plant affect their overall fitness.
