‘Y’ is a plant which does not have Chlorophyll. What could ‘Y’ be ?

The correct option is Cuscuta.

Explanation:

1. Chlorophyll is the green pigment found in plants that enables them to perform photosynthesis and produce their own food using sunlight, water, and carbon dioxide.

2. Cuscuta (commonly known as Dodder or Amarbel) is a non-green parasitic plant that lacks chlorophyll. Because it cannot synthesize its own food, it derives nutrients directly from a host plant by attaching itself to it.

3. On the other hand, Algae, Pitcher plant, and Maple tree all contain chlorophyll and are capable of carrying out photosynthesis (even insectivorous plants like the Pitcher plant have chlorophyll and synthesize their food, using trapped insects primarily for nitrogen intake).

Therefore, plant ‘Y’ is Cuscuta.
