Question

Venus flytrap is sensitive to heat

  1. True
  2. False

hintHint:

It has sensitive trigger hairs.

The correct answer is 'False'.


    The statement is false.
    • They trap prey, mainly insects and arachnids, in trapping structures formed by the terminal part of each plant leaf, triggered by tiny hairs called 'trigger hairs' or 'sensitive hairs' on the inside of the leaf.
    • When an insect or spider crawling along the leaf touches the hair, the trap prepares to close and only closes on further contact within about 20 seconds of the initial attack.
    • A trigger can occur on contact for tenths of a second.
    • The plant only begins digesting after five more rounds of stimulation to ensure that it catches live insects worth eating.
