Differentiate between adaptive and
assistive bioengineered products.
Key concepts/skills:
Level 1: Define key vocabulary.
Level 2: Differentiate between adaptive and
assistive technology.
Level 3: Identify examples of biofuels,
bioengineered medicines, and
bioengineered pest management, and
explain why each is either assistive or
adaptive technology.
Differentiate between adaptive and
assistive bioengineered products.
Key vocabulary:
Bioengineering
Biofuels
Bioengineered food
Assistive bioengineering
Genetic engineering
Gene splicing
Bioengineered medicine
Adaptive bioengineering
Pest management
Differentiate between adaptive and
assistive bioengineered products.
I. Bioengineering
A.The application of
engineering to living things
such as humans and plants
Differentiate between adaptive and
assistive bioengineered products.
1. Assistive Bioengineering
a. engineering that results in a product
or process that helps living
organisms but does not change them
permanently
b. hearing aid, glasses, prosthetic
limbs, band aids
Differentiate between adaptive and
assistive bioengineered products.
2. Adaptive Bioengineering
a. engineering that results in a product
or process that changes
living things
b. artificial heart, artificial organs,
cochlear implants
Differentiate between adaptive and
assistive bioengineered products.

I. Bioengineered Products
A. Medicine – good genes or proteins are
manufacture to replace bad ones
using bacteria
1. Examples- insulin, interferon
2. Genetic engineering – any change to an
organism’s DNA
3. Gene splicing – replacing bad or
undesired genes with
working or desired genes
Differentiate between adaptive and
assistive bioengineered products.
B. In Agriculture – making crops resistant to
disease herbicide and frost
1. Herbicide resistant crops (corn)
2. Plants like tomatoes that will ripen on
vine and stay fresh longer
Differentiate between adaptive and
assistive bioengineered products.
C. Biofuels – Ethanol is a clean burning fuel for
engines made from plants.
1. Cellulose > sugars > ethanol
2. Bacterium control this process
3. Problem is which plants
should be used to make ethanol?
4. Plants used are corn, sugar, sugar
beets, switchgrass, algae
Differentiate between adaptive and
assistive bioengineered products.
