Assertion (A): LHC is useful for photosynthesis in plants

Reason (R): Pigments of LHC make photosynthesis more effective by absorbing different wavelength of light

Assertion is true. The Light-Harvesting Complex (LHC) is a crucial component of the photosynthetic apparatus in plants. It consists of a group of pigment-protein complexes located in the thylakoid membrane of the chloroplasts. The primary role of LHC is to absorb light energy and transfer it to the reaction centers of photosystem I (PSI) and photosystem II (PSII), where the actual process of photosynthesis takes place.

Reason is also true. The pigments in the LHC, such as chlorophyll a, chlorophyll b, and carotenoids, have different absorption spectra. This means they can absorb light of various wavelengths, including blue, red, and some green light. By having pigments with different absorption abilities, the LHC can efficiently capture light across a broad spectrum, maximizing the utilization of available light energy for photosynthesis.

Both A and R are correct and R is correct explanation of A
