HORTICULTURE

Detailed explanation-1: -Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.

Detailed explanation-2: -There are several kinds of chlorophyll, the most important being chlorophyll “a". This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll “a".

Detailed explanation-3: -In the diagram below, you can see the absorption spectra of three key pigments in photosynthesis: chlorophyll a, chlorophyll b, and -carotene. The set of wavelengths that a pigment doesn’t absorb are reflected, and the reflected light is what we see as color.
