Answer 2

The crocus plant is the one which closes its leaves at night.

Explanation:  

This kind of behaviour is called as nyctinasty. These plants act like human beings in terms of circadian rhythms. They fall asleep similarly like human beings sleep, they simply fold their leaves at night like humans close their eyes. This behaviour of this plant is still not known by scientists and it is under research.
