Question
Chapter 22, Problem 2AC
Summary Introduction
To determine:
The reason for the failure of domestication of oaks.
Concept introduction:
Around 2000000 species of plants have been domesticated for human use. Domestication means plant species are grown in farms for the usage of a human. Some species like almonds is nutritious and harmless, but its wild precursor can cause cyanide poisoning. Similarly, people are trying to domesticate oaks for human use.

James is preparing a plate of papaya (Carica papaya) for his sleepover friends. As he cuts open the papaya, they discover numbers of slime-covered seed inside, surrounded by soft flesh and soft skin. Before papaya fruits ripen and the seeds inside them mature, their flesh is bitter or sour. Only later does it become tasty.Discuss how this feature improves the odds for the plant's reproductive success and identify the possible agents to disperse the seeds.

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?

In the 1950s, Asia faced food shortages and an impending famine. If you have relatives that lived in Asia during the ’50s and ’60s, they may tell you that due to the rice shortage, many starved and those who were lucky had to supplement their diet with other crops, such as barley. In 1962, an organization focused on research and development of rice called the International Rice Research Institute (IRRI) developed a high-yielding variety of rice by crossing the two types of rice from Indonesia and China. The result was groundbreaking. The new variety called IR8 (India Rice 8) increased its yield as much as 10 times the traditional variety of rice. By the early 1970s, many rice farmers in India, the Philippines, and Vietnam switched to cultivating IR8 rice, making these countries into major rice exporters, preventing a mass famine in Asia, and saving millions of lives. In many major Canadian cities, a GMO-free, organic diet is becoming more popular, as can…arrow_forward
- A nine-year research and experimentations have successfully developed rice plants with golden hue kernels instead of the usual white kernels. What is the advantage of this modified rice plant? Select one: To make the plant become resistant to herbivores. To provide sufficient rice produce due to its shorter cycle. To add nutritional value to the rice kernels. To allow easy harvesting and processing.arrow_forwardA tree produces only seedless oranges. A small branch cut from this tree produces roots after it is planted in soil.

Roundup is a weed-killing chemical that was produced by Monsanto, (recently purchased by Bayer). The farmer can directly spray Round-up on his fields and it will kill all the weeds, yet leave the soybean plants unharmed. One particular farmer noticed that after a few years of using Roundup weed killer, it became less effective, leaving more andynore weeds alive after spraying. Which of the following explanations, best describes why these weeds remained alive? After years of exposure to Roundup, the soybeans became more resistant to the weed killer. Roundup-resistant weeds were more likely to survive and reproduce than were non-resistant individuals. When Bayer bought out Monsanto, they started selling poor-quality Roundup. Roundup-resistant weeds have less-efficient photosynthetic pathways than the original form.arrow_forwardPlants play a key role in the terrestrial environments of Earth.

- Cucumbers and melons are both members of the genus Cucumis, which includes members with distinct geographical origins: the Asiatic group and the African group. The African members of the genus possess disease resistance not found among the Asiatic members of the same genus, and scientists were interested in creating melon-cucumber hybrids that would possess enhanced resistance to mildew and plant viruses. Plant breeders have nicknamed this new fruit, the “melumber”, but its scientific name is Cucumis hytivus. Please fill in the table attached and answer the following questions. a.) Assuming that the Hoosier cucumber was produced in a laboratory, briefly describe the most likely method by which it was produced and the biological mechanism involved in the action of the agent utilized by the scientists. b.) Suppose scientists wanted to employ an alternative approach to producing cucumber plants that were resistant to the cucumber mosaic virus.

Competition among plants is intense, and research has shown that individual plants compete for space via allelopathy. Imagine that some of the plants (the "mutants") experience a genetic mutation that renders the essential oils in their leaves much less volatile or much less abundant than the essential oils in the plants around them. The most likely outcome for these mutant plants is:arrow_forward
