Lichens Characteristics
Some characteristics of Lichens are listed below:
- Lichens are symbiotic organisms formed by a fungus and a photosynthetic partner (algae or cyanobacterium).
- The body of the lichen do not have a distinct or identifiable root, shoot, or leaf. Hence termed as thallus.
- Lichens exhibit various forms, including crustose, foliose, and fruticose.
- Lichens can tolerate extreme environmental conditions and are found in diverse habitats.
- Reproduction occurs through both sexual (spores) and asexual (soredia) means.
- Some lichen species are bioindicators, reflecting environmental conditions.

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.
