Answer 1

Dear student,

The correct answer is option “A“.

Plant movement occurs due to stimuli (External or Internal) .

The movements occur with response to external stimuli called paratonic movement.

Pitcher plant is a carnivorous plant,

When insect falls on the pitcher for nectar it will be an external stimuli so the closure of lid of pitcher in pitcher plant is due to paratonic movement.
