Venus Flytrap Snap Mechanism: Cell Wall Softening, Not Water Flow
Key Takeaways
- Traditional water-pumping hypothesis disproved by slow water movement (30-60 seconds).
- Cell wall softening on outer epidermal layer enables rapid closure (<1 second).
- Electric and calcium signals act as plant nervous system to trigger softening.
- Discovery opens biomimetic applications in robotics and materials science.
