Chlorophyll (noun)

A green pigment found in the chloroplasts of plants, algae, and some bacteria, responsible for absorbing light energy from the sun and converting it into chemical energy through photosynthesis.

Origin:

Derived from the greek words chloros, meaning 'green', and phyllon, meaning 'leaf'.

Examples:

1. Chlorophyll is the pigment that gives leaves their green color.
2. The process of photosynthesis involves the conversion of light energy into chemical energy with the help of chlorophyll.
3. Chlorophyll helps plants to produce food and grow, absorbing sunlight to power the chemical reactions involved in photosynthesis.
4. Chlorophyll supplements are often marketed as a natural way to improve health and digestion, as they are a rich source of antioxidants and other beneficial compounds.
5. The change of seasons is indicated by the change in the chlorophyll content of leaves, as they turn from green to yellow or red.
