Have you seen growth tips of delicate plants fold in like this, as if in a sleep mode? I have some Myriophyllum simulans that does this. Near the end of a 15 hour light cycle, they close up. After about 8 or 9 hours of darkness, lights go on, and tips still are folded. It takes about an hour and a half for them to open up again.

In the morning leaves open to capture light to photosynthesize and later in the light period they close so they don't fry. At night they turn off their ion pumps and go into resting. Tom Barr says this process is called nyctinasty.
