Jul 11, 2015 · Lichens are a symbiotic partnership between algae or cyanobacteria (the photobiont) and a fungus (the mycobiont). The fungus provides structure and protects the photobiont while the photobiont produces food for both partners through photosynthesis. Lichens have four basic thallus morphologies - crustose, foliose, fruticose, and squamulose.

Jul 11, 2015 · Lichens are a symbiotic association between algae and fungi. The fungal component provides structure and protection while the algal component produces food through photosynthesis. Lichens grow in a variety of habitats including tree bark, rocks, and soil.

Mar 5, 2019 · Lichens are a symbiotic partnership between a fungus and an alga or cyanobacterium. There are estimated to be 15,000-20,000 lichen species that can grow in crustose, foliose, or fruticose forms. Lichens reproduce asexually through structures like soredia, isidia, and soralia or sexually through spores.
