Questions & Answers

Q: Can plants feel?

While plants do not have brains or pain receptors, they do have ways of sensing and reacting to their environment, such as light, touch, gravity, and odors.

Q: How do plants communicate with each other?

Plants may communicate through their roots by secreting carbon-based molecules as signals to warn other plants about poor conditions. They may also share resources through a network of fungi.

Q: Can plants hear?

There is evidence that plants can sense vibrations directly on their leaves, such as vibrations caused by chewing caterpillars. However, it is still unclear whether plants react to the vibrations of sounds.

Q: How can plants be grown on the moon?

Moon dirt lacks essential nutrients for plant growth, but scientists are researching ways to genetically engineer plants to be more moon-tolerant or modify moon dirt to be more plant-friendly.
