Textbook Question
Chapter 40, Problem 2A
Your roommate is taking biology with you this semester and thinks he understands shod- and long-day plants. He purchases one plant of each type and decides to see the difference himself by first trying to cause the short-day plant to flower. He places both plants under the same conditions and exposes each to a regimen of 10-hr days, expecting that the short-day plant will flower, and the long-day plant will not You play a trick on your roommate and reverse the outcome Specifically, what did you have to do?
a. Lengthen the time each is exposed to light.
b. Shorten the time each is exposed to light.
c. Quickly expose the plants to light during the middle of the night.
d. None of the choices is correct.

Urkle decided he wanted to test the effects of watering his plants with cold coffee. For a week he watered one group of plants cold coffee. He ignored the other group of plants. Urkle has no idea what might happen to plants that receive coffee. What is wrong with Urkle's experimental design?
If Urkle wants to test the effects of cold coffee on plant growth, he should water his control group with cold water.
If Urkle wants to test the effects of cold coffee on plant growth, he should water the plants in the other group with Dr. Pepper.
If Urkle wants to test to test the effects of cold coffee on plant growth, he should water the plants in the other group with hot coffee.
If Urkle wants to test the effects of cold coffee on plant growth, he can ignore the control group as long as he makes sure both groups get the same amount of sun.
A long day plant is given a long night, and is interrupted by a light pulse in the middle of the night. Which quality of the light pulse will most likely prevent flowering?
Select one:
a.
UV light
b.
green light
c.
red light
d.
far-red light
Owners and managers of plant nurseries have to plan lighting schedules for a long-day plant that will flower in February. What lighting periods will be most effective? What color of light should be chosen?

Using pollen from a carpelate flower to fertilize a staminate flower would be successful. b. If the plants used gametophytic self-incompatibility, half of the pollen would be successful. c. If the plants used sporophytic self-incompatibility, half of the pollen would be successful. d. Pollen from an S2S5 plant can never pollinate an S1S5 flower.arrow_forwardAlex thought that flower formation must be dependent on water. If this was true, he expected that the more water plants got, the more flowers they would produce. In order to test this, he obtained 200 identical petunia plants. He separated these into twenty groups of 10 plants each. He re-potted each petunia into identical containers, using the same bag of potting soil. He placed each group of plants in a large open field with no shade. Group 1 received only rain water. Each of the other groups received 10 additional ml of water, plants in group 3 received 20 additional ml of water and so on, so that plants in group 20 each received a total of 190 ml of water each evening, in addition to the rainwater. The plants were allowed to grow under these conditions for three months. When the plants bloomed, Alex recorded the number of blossoms on each petunia.
