Please someone help me to make a list of 20 or more iteams we use or we have around our house or around us that comes from plant, you dont have to go into details just make list.just like potatoe-comes form potatoe plant. 1)Take a walk around your house and make a list of 20 or more specific items that come from seed plants. Specific means you should not write “food”—instead, write a specific food, like potatoes. If you want to write five specific foods, go ahead. You can also include non-food plant products, such as the cotton in your T-shirts or the wood in your floors. 2)2. Then write down what plant each item comes from. This can be the common name, for example, potatoes come from potato plants and the wood in your floor comes from trees (it’s ok if you don’t know exactly what kind of trees your floor comes from). Thank you

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. Indvioual potted plants were kept in separate seated containers with an initial level of TCE (trichloroethytene) around 15.0C0 micrograms per cubic meter of air. Samples of the air m 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. 1. How many transgenic plants did the researchers test?
