Unlike conventional plants, the Venus flytrap copes with poor soil by eating bugs! But the cost of insect hunting is high. Catching prey requires
Dionaea muscipula to snap down quickly and then carry out the energy-intensive process of digestion. To balance the costs and benefits of eating meat, the plants have developed a
counting system to identify real prey from false alarms, according to a new study.
To understand how the flytrap distinguishes a potential food source from a false alarm like a raindrop, researchers observed the electrical and chemical response of the plant to touch stimulation. In order to mimic insect prey, the scientists stimulated the hairlike sensors located on the plant’s trap. Touching the sensors two times quick ...
