Question

how were the trees trying to make themselves free​

Answer 1

The leaves tried hard to reach the window of glass so that they could go outside. Even the small stems of the trees put much of their effort in order to set themselves free. The big branches were also trying a lot to go out from the roof of the room.

The roots of the trees work all night to disengage themselves from the cracks in the veranda floor. The leaves exert a lot of force on the glasses to break them and the twigs become stiff with exertion.
