You have heard about several insectivorous plants that feed on insects. Nepenthes or the pitcher plant is one such example, which usually grows in shallow water or marshlands. What part of the plant is modified into a ‘pitcher’? How does this modification help the plant for food even though it can photosynthesize like any other green plant?

Answers (1)

The leaves of the pitcher plant are modified into a pitcher. The pitcher is facilitated with a lid which is developed from the tip of the lamina. The anterior part of the petiole is coiled like a little tendril. It helps to keep the pitcher in a vertical position. The leaf lamina is modified into the pitcher and it produces digestive juices. Insects and other prey are attracted to the mouth of the pitcher where nectar-secreting glands line the lip of the pitcher. The pitcher is very slippery in nature which makes the insect slide into the digestive juices that are present inside the pitcher. Hence, this modification helps the plant with food.
