Klorofill, or chlorophyll, is a green pigment found in plants, algae, and some bacteria. It plays a crucial role in photosynthesis, the process by which these organisms convert sunlight into energy. Chlorophyll absorbs light most efficiently in the blue and red wavelengths, reflecting green light, which is why plants appear green. There are two main types of chlorophyll: chlorophyll a and chlorophyll b. Chlorophyll a is essential for the photosynthetic process, while chlorophyll b assists by capturing additional light energy. Together, they enable plants to produce oxygen and glucose, supporting life on Earth.
