Chlorophylls a and b are abundant in green plants, and c and d are found in some protists and cyanobacteria. A number of different types of bacteriochlorophyll have been found; which type of chlorophyll is the most widely distributed, shows the distribution of pigments in different types of photosynthetic organisms;

The quantum yield of photosynthesis falls off drastically for far-red light of wavelengths greater than 680 nm, indicating that far-red light alone is inefficient in driving

photosynthesis, this effect is called
