Q. The ability of the venus flytrap to capture insects is due to :
A) chemical stimulation by the prey
B) a passive process requiring no special ability on the part of the plant
C) specialized "muscle-like" cells
D) rapid turgor pressure changes
Explanation
[Solution from source] When an insect touches the trigger hairs, the cells of the leaf lobes rapidly lose or gain turgor (and expand quickly), so the trap snaps shut. Plants have no muscle cells, and the closure is an active response to touch, not to a chemical. Answer (4).
