Question
Chapter 27, Problem 4CT
Summary Introduction
To determine:
The reason for higher concern for the hormones injected into the animals for increasing yield of animal products than on the plant's hormones that increase the yield of plant products.
Introduction:
The phytohormones are the chemical compounds released by the plants that influence various physiological processes in the plant like growth, development, senescence, abscission, cell division and so on.

Cattle in industrial dairy farms are typically given rBST, an animal hormone that increases a cow’s milk production. There is concern that such hormones may have unforeseen effects on milik-drinking humans. Why is there much less concern about plant hormones in the plant foods we eat?
Briefly define what a plant hormone is. Also, explain, using an example for each, of how hormones can both work together and work against each other when they are received by a particular part of a 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 and notice that while there are many fruits on the apple tree, they seem to remain hard, sour, and green. Your club mates need the red, sweet apples in just a few days for the apple competition.
Choose the best hormone to apply and the reason supporting its use:
Select one:
a. Apply ethylene to the apples to increase ripening.
b. Apply ethylene to slow ripening and increase chlorophyll levels.
c. Apply auxin to increase parthenocarpy
d. Apply gibberellins to increase fruit size.
e. Apply auxins to decrease apical dominance and increase water intake.

- Plant growth... hormones only have very specific, limited functions is centrally regulated by the plant nervous system only involves hormones made at the site of action can vary in response to environmental conditions all of the abovearrow_forwardScientists studied changes in proline, which is an indicator of plant stress and overall protein content in the corn plant when leaves had been consumed by grasshoppers. Corn plants were exposed to varying numbers of grasshoppers and compared to control plants with no grasshopper exposure. The bar graphs, with error bars, show the mean proline and protein content. The dashed lines show the proline and protein content of healthy plants 10 days prior to treatment. Which of the following statements would most likely describe the growth of corn plants in this study? When there is a decrease in the number of grasshoppers (dependent variable) measured against proline and protein content (independent variables), the corn plants would have slower growth and be smaller than the control plants. When there is an increase in the number of grasshoppers (dependent variable) measured against proline and protein content (independent variables), the growth of the corn plants would be similar…arrow_forwardWhich of the following is not a characteristic of plant hormones?

- 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: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? Ethylene Abscisic acid (ABA) Gibberellins Auxin Strigolactone Cytokininarrow_forwardWhich of these are plant hormones? Starch Nicotine Palmitic acid Ethylenearrow_forward
