A) A signal is sent after a fly touches any of three or four small trigger hairs on the leaf pad.
B) Neurons send a signal to close leaf pads.
C) Intercellular electrical signals collapse the leaf pads by rapid change in turgor pressure.
D) a and b
E) a and c

Question

Quizplus · Accepted Answer

A Venus flytrap responds to stimuli when a fly or other small insect touches one of the trigger hairs on the leaf pad, not three or four as stated, but touching twice is the usual trigger. This contact generates an electrical signal that changes the turgor pressure in the cells at the hinge of the trap, causing it to close rapidly. Neurons are not involved in this process as they are in animals; instead, the plant uses intercellular electrical signals.
