Banana and GMO Knowledge Assessment

The video explores the history of genetically modified organisms (GMOs), highlighting how humans have been altering the genetics of plants and animals for thousands of years. It discusses the domestication of corn, the genetic mutation of almonds to make them safe to eat, and the cultivation of bananas, including the challenges faced due to diseases. The video concludes with a discussion on modern GMOs and their impact on agriculture.

What is a common misconception about genetically modified organisms (GMOs)?

• They are only found in processed foods.

• They are always harmful to health.

• They are a recent invention.

• They are only created in high-tech labs.

How did ancient peoples transform teosinte into the corn we know today?

• By cross-breeding with other grains.

• By using chemical fertilizers.

• Through selective breeding.

• Using modern genetic engineering techniques.

What was a significant factor in the development of larger and sweeter corn in South America?

• Isolation from teosinte grasses.

• Cross-pollination with teosinte.

• Introduction of new fertilizers.

• Cyanide

• Amygdalin

How did ancient humans make almonds safe to eat?

• Through selective breeding.

• By boiling them.
