How does genlisea trap its prey?

Genlisea, a genus of carnivorous plants, traps its prey primarily through specialized underground traps known as "tubers." These structures have modified leaves that create a suction mechanism when small aquatic organisms, like protozoa, enter. The traps have a narrow opening and a smooth, slippery interior that prevents escape, allowing the plant to absorb nutrients from the trapped prey. This adaptation enables Genlisea to thrive in nutrient-poor environments.
