Chlorophyll c is a type of pigment found in some algae and photosynthetic organisms. It is responsible for absorbing light energy during photosynthesis. If you're looking for synonyms for chlorophyll c, you may also come across terms like phycobilin, phycoerythrin, and phycocyanin. These are alternative pigments found in some types of cyanobacteria and red algae, and they help to capture light energy in a similar manner to chlorophyll c. Other potential synonyms for chlorophyll c could include accessory pigments or photopigments, but these terms are more general and may refer to a wider range of pigments involved in photosynthesis.
