Glow-in-the-Dark Plants on the ISS Quiz

What is the primary focus of the experiment conducted on the ISS with genetically engineered plants?

• To test the effects of radiation on plant DNA

• To study plant growth in different soil types

• To observe plant responses to microgravity

• To develop new plant species for space farming

What is the purpose of the glowing modification in Arabidopsis thaliana?

• To enhance photosynthesis efficiency

• To indicate when the plant is under stress

• To track plant growth rates

• To make the plants more visually appealing

What unexpected result was observed regarding the plant hormone auxen in the TAGES experiment?

• It was found in the leaves instead of the roots

• It caused the plants to stop growing

• It appeared in the hypocotyls instead of the root tips

• It was absent in the plants grown in space

How did Arabidopsis thaliana use light in the absence of gravity?

• To enhance its photosynthesis process

• As a substitute for gravity to determine direction

• To increase its growth rate

• To change its color for camouflage

What does the adaptability of Arabidopsis in space suggest for life on Earth?

• Space conditions are too harsh for any plant life

• Plants can adapt to new and challenging environments

• Plants may not survive in changing climates

• Only genetically modified plants can adapt to changes
