Question

How does a pitcher plant trap insects?

Answer 1

Pitcher plant is an insectivorous plant that derives nitrogenous compounds by trapping and consuming insects. The leaf of a pitcher plant is modified to form a pitcher-like structure. When an insect sits on the pitcher, the lid of the pitcher gets closed and the insect gets trapped inside. The insect is then digested by the enzymes secreted by the plant. In this manner, pitcher plants fulfil their requirement of nitrogen by feeding on insects.
