- TCE Uptake by Transgenic Plants Plants used for phytoremediation take up organic pollutants, then transport the chemicals to plant tissues, where they are stored or broken down. Researchers are now designing transgenic plants with enhanced ability to take up or break down toxins. In 2007, Sharon Doty and her colleagues published the results of their efforts to design plants for phytoremediation of soil and air containing organic solvents. The researchers used Agrobacterium tumefaciens (Section 15.7) to deliver a mammalian gene into poplar plants. The gene encodes cytochrome P450, an enzyme involved in the breakdown of a range of organic molecules, including solvents such as TCE. FIGURE 28.16 shows data from one test on the resulting transgenic plants. FIGURE 28.16 TCE uptake from air by transgenic poplar plants. Individual potted plants were kept in separate seated containers with an initial level of TCE (trichloroethylene) around 15,000 micrograms per cubic meter of air. Samples of the air in the containers were taken daily and measured for TCE content. Controls included a tree transgenic for a Ti plasmid with no cytochrome P450 in it (vector control), and a bare-root transgenic tree (one that was not planted in soil. 4. Assuming no other experiments were done, what two explanations are there for the results of this experiment? What other control might the researchers have used?TCE Uptake by Transgenic Plants Plants used for phytoremediation take up organic pollutants, then transport the chemicals to plant tissues, where they are stored or broken down.

- The Irish potato famine was an important historical event that occurred in the 1840’s. The Irish were generally low income, and relied entirely on a particular variety of potato, known as "lumpers”. This strain of potato was susceptible to a rot caused by Phytophthora infestans. This led to wide-spread potato spoilage, which devastated the food supply, and ultimately caused many deaths. What would have been an effective strategy to avoid the Irish potato famine? Plant a more diverse mix of potatoes. Use antibiotics on the potatoes to protect from the rot. Expand cropland to increase the total number of potatoes grown. Use fertilizers, crop rotation, and irrigation to improve potatoes crop yields.Which of the following is not an adaption that helps plantsresist gravity and/or dry conditions on land?a. xylemb. ligninc. cuticled. photosynthesisPhytochemicals are plant components not essential but they provide us with health benefits plant component regarded as essential for our body animal products necessary for human health plant components that our body cannot use plant proteins and carbohydrates
