Correct answer: B. Fungi and Green Algae
- A. Fungi and Nematodes
- B. Fungi and Green Algae
- C. Fungi and roots of vascular plants
- D. Fungi and viruses
- E. Fungi and fungi
Explanation
The correct option is "Fungi and Green Algae." Lichens are composite organisms that result from a mutualistic relationship between a fungus and a photosynthetic partner, typically green algae or cyanobacteria. The fungus provides a protective shelter and absorbs water and nutrients, while the green algae or cyanobacteria perform photosynthesis to produce energy-rich compounds. This mutually beneficial association allows lichens to thrive in a variety of habitats, including harsh environments such as deserts and rocky surfaces.
