Question
True or False
Lichens are formed from a combination of a fungal partner (mycobiont) and an algal partner (photobiont).
Group of answer choices
- True
- False
Solution
True.
Lichens are indeed symbiotic organisms formed from a partnership between a fungal component, known as the mycobiont, and a photosynthetic partner, typically an alga or cyanobacteria, referred to as the photobiont. This unique relationship allows lichens to thrive in various environments, often in harsh conditions where neither partner could survive alone.
In this symbiosis, the fungus provides a protective structure and absorbs water and minerals, while the photobiont conducts photosynthesis to produce organic compounds, which serve as a source of nutrition for both partners. This mutualistic relationship is crucial for the survival and ecological success of lichens, and they play significant roles in ecosystems, such as in soil formation and serving as bioindicators of environmental health.
