Question
Chapter 24.4, Problem 2MC
Summary Introduction
To determine:
How does a plant hormone exert its effects.
Concept introduction:
Plant hormones are the type of biochemical, which are synthesized in small amounts in the plants. These hormones are synthesized in one part of the plant, and transported to another location of the plant.

- You have been chosen as the lead student gardener for the CSUMB Future Farmers of America Club (FFAC). Your club is looking to you and your Bio211 plant experience to guide them. You arrive at the new FFAC garden plots where your club mates are trying to grow carrots . However, you find that the seeds are not germinating. Which hormone do you think is might be in an excess amount and preventing the seeds from sprouting? Select one: a. Ethylene b. Auxins O c. Gibberllelins O d. Abscisic Acid O e. Cytokininsarrow_forwardWhat is an example of a protein hormone?arrow_forwardAll known hormones in plants are regulated by proteasomes. Which of the following describes the molecular mechanisms that promote increased levels of hormones in plants? Select one: a. synthesis of a suppressing molecule b. degradation of the promoting molecule c. synthesis of a promoting molecule d. degradation of a suppressing moleculearrow_forward
- How do plants adapt to their environment, and what role do plant hormones play in this process?arrow_forwardIt 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?

Using your knowledge of plant hormones, how and why will this affect the remaining buds on the shrub shoot and the future growth of the plant aboveground and belowground.arrow_forwardHormones and signal pathways Complete the following paragraph to describe signal transduction as it occurs within plants. Choices may be used more than once or not at all. Chemical signals called play an important role in a plant's ability to respond to a stimulus. These signals bind to receptors, the first step in a cellular response called a may be located in the plasma membrane, the cytoplasm, the nucleus, or the endoplasmic reticulum. The series of relay proteins or enzymes activated by the hormone binding the receptor make up the Some responses are immediate, while others require a like Ca*, to initiate a cellular response. The result of the transduction pathway is a which is often the transcription of specific genes, resulting in some measurable change. hormones reflex arc signal transduction pathway Signal transducers second messenger response Receptor proteins first messengerarrow_forward
