How Does a Pitcher Plant Digest Insects?

Pitcher plants digest insects with the help of digestive enzymes.

Once the insect gets inside the plant, sarracenia produces digestive juices through the walls. It breaks down the insect and absorbs the nutrients. The plants essentially get nitrogen from the insects. The wall of the pitcher plant is also able to absorb few nutrients and send them directly to the rhizome.

How Does a Pitcher Plant Eat Insects?

The insect stays inside the plant forever as the plant is not able to break down its food completely. Once the pitcher is dried and falls off from the plant the insect remains are eliminated and goes to the soil. The pitcher plant may catch more than one insect at a time but cannot digest them all. This is why some of the pitcher plants turn brown at the stem as the digestive system stops the process as there are more than enough nutrients for the plant. It is noticed that usually the plants kept outdoors tend to catch too many insects.
