Photosynthetic Pigments

Photosynthetic pigments are molecules, such as chlorophyll and carotenoids, that absorb light energy and play a crucial role in the process of photosynthesis by capturing sunlight and converting it into chemical energy. Chlorophyll primarily absorbs blue and red wavelengths, while carotenoids absorb light in the blue-green and violet range, contributing to the overall efficiency of photosynthesis and providing coloration to plants.

Key Terms

Chlorophyll
A green pigment found in plants that absorbs light for photosynthesis.

Example: Chlorophyll gives leaves their green color.

Carotenoids
Pigments that provide yellow, orange, and red colors in plants and help in light absorption.

Example: Carotenoids are responsible for the orange color of carrots.

Photosynthesis
The process by which green plants use sunlight to synthesize foods from carbon dioxide and water.

Example: Photosynthesis produces oxygen as a byproduct.

Light Absorption
The process of capturing light energy by pigments.

Example: Plants absorb sunlight through chlorophyll.

Photosystem
A complex of proteins and pigments that plays a key role in photosynthesis.

Example: Photosystem II is involved in the light-dependent reactions.

Spectrum
The range of different colors of light, each with different wavelengths.

Example: The visible spectrum includes red, orange, yellow, green, blue, indigo, and violet.
