Which one of the following is an insectivorous plant?

Passion flower plant

Pitcher plant

Night queen

Flame of the forest

Correct Answer: Option B

Explanation

1. An insectivorous plant is a carnivorous plant that derives some or most of its nutrients from trapping and consuming insects and other arthropods. 2. Pitcher plants (belonging to families like Nepenthaceae and Sarraceniaceae) have modified leaves known as pitfall traps – pitcher-shaped structures containing digestive fluids that drown and digest trapped insects. 3. Passion flower plant, Night queen (Cestrum nocturnum), and Flame of the forest (Butea monosperma) are not insectivorous. 4. Therefore, the Pitcher plant is an insectivorous plant.
