Chapter 41, 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.
You are responsible for landscaping a very large urban park. You choose a popular flowering garden plant, the hydrangea, to plant throughout the park. The nursery you purchased the plants from said that the flowers should be pink. After a few months, though, you find—to your surprise—that the plants throughout the park display a variety of flower colors ranging from purple and blue, to pink and white, and finally, to all shades in between.
After a suggestion from a friend, you test the soil where each plant was planted, and you determine that the color of the flowers seems to correlate with the acidity of the soil in which the plant was placed.
Choose the answer that best fits the blank. The parentheses after the blanks are the choices.
Since the flowers have shown such a broad range of colors, with no clear distinction between one color type and the next, this is an example of _________ (continuous variation, codominance, pleiotropy). The acidity of the soil is an example of…
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 show you their cherry tree that they've been having trouble with. Originally, its leave would change color and fall off the tree, as expected, in the autumn. However, more recently the leaves started changing color and falling off in the spring time.
Which hormone does the tree likely have in excess and why?

- Under which of the following conditions would pollen from an S2S5 plant successfully pollinate an S1S5 flower? a. 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.

What does this indicate about the pollination process and success? A) 100% success: 100 pollen grains grew to 50 ovules, two to each, and double fertilization occurred. B) 100% success: Only 50% of the pollen grains germinated, but each produced 2 sperms to complete double fertilization in 50 seeds. C) 50% success: 50 sperm fertilized 50 eggs, and 50 sperm fused with 50 polar nuclei.
