Do plants breathe? – part 1

Sheena and Josh, 4th standard students, went on a nature camp with their classmates and Science teacher. After dinner, Sheena found Josh sleeping under a tree. Alarmed, she woke up Josh, “We should not sleep under a tree at night!”

Josh – Oh! What? Why can’t I sleep under a tree in the night?

Sheena – Because in the night, plants take in oxygen and give out carbon dioxide. If you sleep under a tree at night, you will suffocate!

Josh – I don’t believe you. I am not at all suffocating.

Both of them then decided to ask the Science teacher.

The Science teacher asked if it was okay to sleep under a tree during the day, and Sheena said, “Of course! During the day plants take in carbon-dioxide and give out oxygen, so it is fine.” Now it was the teacher’s turn to look surprised.

She asked Sheena, “Do plants breathe?”
