Show answer and explanation

Correct answer: (c) Bacteria

Explanation

The visible Photosynthetically Active Region (PAR) for green plants is 400-700 nm.

Some bacteria (green sulphur, purple and Heliobacteria) use the invisible near-infrared part of sunlight for photosynthesis.

Trees, algae and fungi do not exploit the invisible spectrum, and fungi lack chlorophyll entirely.
