AP BIOLOGY

Detailed explanation-1: -Answer: The non-growth movement in response to an environmental stimulus is called nastic movement. The venus fly trap shows a response to the stimulus of touch when the insect sits on it by closing its leaves.

Detailed explanation-2: -The Venus flytrap Dionaea muscipula captures insects and consumes their flesh. Prey contacting touch-sensitive hairs trigger traveling electrical waves. These action potentials (APs) cause rapid closure of the trap and activate secretory functions of glands, which cover its inner surface.

Detailed explanation-3: -These are the mechano-motion detectors and are extremely sensitive to mechanical stimuli. As seen in this real-time video, other parts of the leaf fail to elicit a response but when the hair cells are touched 2 times in succession, the leaf slams shut on the chance that a living insect might be caught.

Detailed explanation-4: -The Venus flytrap (Dionaea muscipula Ellis) responds to mechanical stimuli imparted by moving insects, which are detected by sensory hairs located on the upper epidermis of the flytrap’s bilobed leaves (Darwin 2014).

Detailed explanation-5: -The leaf trap in a Venus fly trap uses a complex series of steps to trap any insect that lands on it. Much of this process is still poorly understood. However, what we do know is that when a fly sits on the leaf, there are touch-sensitive hairs that trigger an electrical potential.
