Chlorophyll

엽록소

Definition

The green pigment found in chloroplasts that captures light energy to drive photosynthesis in plants and algae.

Detailed Explanation

There are multiple chlorophyll types — chlorophyll a (blue-green), b (yellow-green), c, and d — that absorb different light wavelengths, broadening the usable spectrum. Accessory pigments like carotenoids absorb additional wavelengths and transfer energy to chlorophyll. Chlorophyll reflects green light — this is why plants appear green. Degradation of chlorophyll in autumn reveals underlying carotenoid pigments, creating fall foliage colors.
