Hu Q&A丨You sleep at night, what do plants do at night?

In the morning, I pass through the fields and take a deep breath of fresh air.

Then I rubbed a drop of water on my trouser legs...

Maybe someone will answer:

"I know, it's dew."

But is this really the case?

Except for the dewdrops,

In what other ways do plants "spit out water"?

Why is this so?
