Plants can, and do, respond to stimuli. However this is only an indication
that they are alive and in no way suggests the presence of a brain in the
way that we understand.
Only intentionally silly questions are deemed silly.

Hi,

It may seem a silly question but I have heard that the plants have
"lesser brain", the seat of instincts.

Is it true?
