Many plants are capable of responding very rapidly to mechanical stimuli. For instance, Venus Flytraps respond more quickly than their insect prey can escape. A very mild touch or a light breeze can cause the leaves of the Sensitive Plant to close tightly. This rapid transmission of touch is accomplished by .

The rapid transmission of touch is accomplished by leaves.

Explanation:

The leaves are wide and contain short stiff hairs which are highly sensitive to touch.

When an insect comes closer to the leaves,it remains open for some second.When trap closes over food,the cilia which are finger like projection keeps larger insect inside and the trap shuts quickly to keep the digestive fluids inside and bacteria outside.

They secrete digestive juice that dissolve the inner part of the insect but they are not capable of dissolving the outer part or exoskeleton.

This depends on the size of the insect,temperature,and the number of time they have gone through the process.

After ingest the nutrients, the trap opens and they release the undigested insect part out of their body.
