Why are Pitcher plants heterotrophs?
Question



Why are Pitcher plants heterotrophs?

A.

They do not contain chlorophyll in their leaves.

B.

They do not get sunlight.

C.

They do not get nitrogen from the soil

D.

They do not get water from the soil

Correct option is C


The correct answer is They do not get nitrogen from the soil.
· The pitcher plant performs photosynthesis which makes it an autotrophic plant, but it also has a partial heterotrophic mode of nutrition because the pitcher plant grows on nitrogen-deficient soil.
· Carnivorous plants obtain the essential nutrients from the heterotrophs.
Additional Information
· The pitcher plant is an insectivorous plant
· It has a Pitcher-like structure that is the modified part of the leaf.
· The apex of the leaf forms a lid that can open and close the mouth of the pitcher.
· Inside the pitcher, there are hairs that are directed downwards.
· When an insect lands in the pitcher, the lid closes and the trapped insect gets entangled into the hair.
· The insect is digested by the digestive juices secreted in the pitcher.
· It can trap and eat frogs, insects, and even mice.
· It is found in Australia, Indonesia, and Meghalaya in India.
· It has a pitcher-like shape and the mouth is covered by a leaf.
· It has a special smell that attracts insects to it, which get trapped and can't get out.
Thus, the pitcher plant is an insectivorous plant.
