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?
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:
O a. Apply ethylene to the apples to increase ripening.
O b. Apply ethylene to slow ripening and increase chlorophyll levels.
O C. Apply auxin to increase parthenocarpy
O d. Apply gibberellins to increase fruit size.
O 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 above

- Scientists 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_forward2,4-D and 2,4,5-T are examples of hormonal-based herbicides.
