Quick Summary

The term "phycobiont" refers to the algal or cyanobacterial partner in a symbiotic relationship with a fungus, forming a lichen. This phycobiont is responsible for photosynthesis, providing carbohydrates and vitamins essential for the fungus's survival. In return, the fungus offers protection from environmental extremes, absorbs water vapor, and provides shade for the phycobiont. Lichens are composite organisms, and the phycobiont is a crucial component of their structure and function.12
