Bioengineering
The development of technology in the
fields of biology and medicine.
Bioengineers have helped create new
technology such as
Bioengineered products also help doctors treat
diseases--ex. diabetes
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!
Assistive
technology
Adaptive technology
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.
Helps to change a plant’s genetic make-up to protect
them from diseases, frost and herbicides.
What is a 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!
Gasoline for most cars
and vehicles
contain ethanol.
A form of alcohol!
Ethanol is a biofuel—a fuel made of recently living
things—not fossil fuels!
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.
