Bioengineering The development of technology in the fields
Bioengineering The development of technology in the fields of biology and medicine. Bioengineers have helped create new technology such as RI r M ne an sc g T n C ni e n in a h c c s a M
Bioengineered products also help doctors treat diseases--ex. diabetes
Bioengineers also design devices to help people with disabilities! Assistive devices-- Helps the disabled with their daily lives. Adaptive devices-- Aid the disabled and actually changes the user.
Lets take a closer look at the difference in these technologies! crutches Cochl ear im plants Assistive technology es s n e ct l Adaptive technology y ta Con e y E k i as L Hear ing a id er g r u S
Bioengineering in agriculture! Farmers always want to grow the best/most successful crops! Examples: 1. Crops that are resistant to disease. Engineers use bacteria to carry useful genes into plants. Gene – Tiny part of a cell that gives a living thing a certain trait. Helps to change a plant’s genetic make-up to protect them from diseases, frost and herbicides. What is an herbicide? Substance used to kill weeds!
2. Plants are altered to stay fresh longer. Bioengineers found a way to make tomatoes ripen more quickly on the vine and lengthen their shelf life. 3. Plants may grow by using less water. 4. Crops that taste better, stay fresh longer, or are more nutritious. Can bioengineering plants be too successful? Resistance to herbicides—good and bad? Too much of a engineered plant—everyone suffers!
Bioengineers are always looking for ways to supply us with necessary fuel/gasoline. Gasoline for most cars and vehicles contain ethanol. A form of alcohol!
Ethanol is added to gasoline to replace the oil. Ethanol is a biofuel—a fuel made of recently living things—not fossil fuels!
Ethanol is made from the part of the plant known as cellulose (substance that makes up the tough fibers of a plant). Ethanol can be made in two ways: 1. Bioengineered bacteria help make ethanol from corn plants. 2. Ethanol can also be made from plants with large amounts of vegetable oil -soybeans.
Number your paper as follows: Name of device Assistive or Adaptive 1. -- 2. -- 3. -- 4. -- 5. -- As each picture appears write the name of the device in the first column and whether it is assistive or adaptive in the second column.
1. Assistive or Adaptive 2. Assistive or Adaptive
3. 4. Assistive or Adaptive
5. Assistive or Adaptive 6. Name two plants that can be used to make biofuels.
