Question

The plant which traps and feeds on insects is

• A. Cuscuta
• B. China Rose
• C. Pitcher Plant
• D. Rose

Answer 1

The correct option is C

Pitcher Plant

The correct option is C.

Explanation of the correct option:

1. These plants are attractive. They generally attract insects through their odor and color.
2. They have a jar and lid-like mechanism which closes the lid when the insect gets to sit on it.
3. They also have a digestive enzyme inbuilt which digests the insect when it gets trapped in it and gets digested.

Explanation of the incorrect option:

Option A:

1. Cuscuta are parasitic plants.
2. They cannot produce their food as they don't have the green pigment called chlorophyll.
3. So, they, therefore, depend on other plants for their essential nutrients, and hence they depend on the host for food and hence don't use the mechanism of trapping insects and animals.

Option B:

1. China Rose is generally autotroph by nature.
2. They can readily prepare their food using photosynthesis as they contain the pigment chlorophyll.
3. Hence they don't use the mechanism of trapping their prey.

Option D:

1. They are also autotrophs.
2. So, they need not depend on other species for food and hence can prepare their food by the process of photosynthesis.
3. Hence they don't use the mechanism of trapping their prey

Final Answer: the plant which traps and feeds on insects is the pitcher plant.
