What are Lichens?
Definition of Lichens: Lichens are symbiotic association between a fungus and an algae. The fungal partner helps in absorption of nutrients and in reproduction whereas algal partner helps in photosynthesis.
Lichens meaning a group of plant-like organisms formed when a symbiotic relationship is established between a fungus and a photosynthetic partner, typically algae or cyanobacteria that contain chlorophyll. Symbiosis is a process in which two organisms associate with each other and mutually benefit from the association. Lichens are model organisms that show symbiotic association.
This association creates a composite organism where the lichen fungus provides structural support and protection while the photosynthetic partner produces energy through photosynthesis. Usually, the fungal part is the dominant partner that gives the lichens most of its morphological and reproductive characteristics.
Lichens
Lichens, also known as lichen trees or lichen plants, are symbiotic associations between fungi and algae or cyanobacteria. The lichen types include – lichen crustose, lichen foliose, and lichen fruticose. Lichen is an example of mutualism.
The fungal component provides structure and protection, while the algal or cyanobacterial component contributes through photosynthesis. Lichens are highly adaptable and thrive in various environments, from arctic tundras to deserts.
Lichens play ecological roles such as soil stabilization, nitrogen fixation, and contributing to primary succession on bare substrates. In this article, we will read about Lichens, their general characteristics, structure, types, classification, and significance of lichen.
