What are biotech foods?
Biotech foods are completely natural and unaltered.
Biotech foods are made in laboratories without any real plants.
Biotech foods are made only from fruits and vegetables.
Biotech foods are produced from animals and plants that have been genetically altered.
How have humans traditionally altered plant genetics?
By cooking food longer.
By saving seeds and breeding varieties with better traits.
By freezing plants in special labs.
By using only chemicals.
How is genetic engineering different from traditional breeding?
It allows transferring just a few genes between unrelated species.
It mixes all the genes randomly.
It requires the use of robots.
It only works with animals.
What is one surprising example of modern genetic engineering?
Banana genes in rice to make it sweet.
Human genes in tomatoes to grow faster.
Spider genes in grapes to make webs.
Rat genes inserted into lettuce to produce vitamin C.
Why are GE corn varieties considered possibly safer than regular corn?
They are sweeter.
They grow faster.
They have lower levels of fumonisins, a harmful toxin.
They are cheaper to grow.
What happened with modified soybeans in the 1990s?
They turned brown too quickly.
They were banned for being too expensive.
They contained a protein that could cause allergic reactions.
They grew too fast.
What is one concern critics have about GE foods?
GE foods will taste too strong.
Moving genes between unrelated species might cause unexpected health effects.
People won’t like the color of GE foods.
They will be too hard to find in stores.
What is the main environmental concern with GE crops?
They grow too large.
They are too colorful and attract animals.
They may harm the environment if not tested enough.
They are harder to harvest.
How can GE crops possibly help fight world hunger?
They grow only in cities.
They can grow in dry climates and poor soils.
They replace all other food.
They can be eaten without cooking.
Why are some experts doubtful about golden rice?
It might not help people who are malnourished.
It is too expensive to produce.
It grows only in cold places.
It tastes bad.
