Question

The ability of the Venus Flytrap to capture insects is due to -

• A. Rapid turgor pressure changes
• B. A passive process requiring no special ability on the part of the plant

• D. Chemical stimulation by the prey

Answer 1

The correct option is A Rapid turgor pressure changes

Venus flytrap is a type of insectivorous plant. It gets Nitrogen from the insect. It has the specialized leaves to capture insects. The leaves have winged petiole with toothed jaws. The upper surface of the jaw contains hairs, which are very sensitive to touch stimuli. When an insect touches these hairs, then there is a rapid change in the turgor pressure.
