Explain the mechanism of trapping insects in Venus flytrap
Asked by sachetametha | 02 Jun, 2019, 10:04: AM
Expert Answer
1. Each side of the trap has three to four sensory hairs, each no longer than 0.2 inches (0.5 centimeters).
2.The first time a hair is triggered, it creates an electrical signal that travels along the surface of the trap, much like the electrical signal that travels through an animal's nerve cell.
3. During the second signal, cells in the center of each lobe lose water along with the ions. This causes the cells to lose turgor, the water pressure that keeps a plant rigid. As a result, the lobes snap together.
4. After the trap has snapped shut, the plant turns it into an external stomach, sealing the trap so no air gets in or out.
