Differnitiate between homoimerous and heteromerous lichens
Dear Student,
Lichens are the organisms that are formed by the symbiotic association of the filamentous fungus (mycoboint) and the microscopic green algae or cyanobacteria (the photoboint or phycoboint). Fungus provides attachment, moisture, minerals to algae & in turn algae provides food through the process of photosynthesis.
There are two types of homoiomerous and heteromerous.
Homoiomerous Lichens - It is simplest lichen having simple thallus. It contains loosely arranged hyphae and shows little differentiation (uniform). For example - Leptogium and Collema
Heteromerous Lichen - It is complex form and consists of differentiation of thallus can be seen. The algal component are confined to specific locations. It has compactly and densely packed fungal hyphae. It has following zones: Upper cortex (thallus), algal zone (algae), medulla (loosely arranged fungal partner) and lower cortex (dense fungal hyphae). Example - Parmelia
Hope this information will clear your doubts about topic.
