Association between mycobiont and phycobiont are found in
(a) mycorrhiza (b) root (c) lichens (d) BGA
Lichens are dual organisms that have a permanent symbiotic association of a fungus and an alga. The fungal partner is called mycobiont and the algal partner is called phycobiont.
Mycorrhiza is associated with a fungus with roots, but not with algae, while BGA is a blue-green alga a member of Monera having a prokaryotic cell.
