Lichen is a symbiotic mutualistic association of fungi with______________?
Correct answer: C. Green algae and cyanobacterium
- A. Autotrophs
- B. Roots of vascular plants
- C. Green algae and cyanobacterium
- D. Leguminous plants
Explanation
A lichen is a mutualistic association between a fungus and a photosynthetic partner, usually a green alga or cyanobacterium. Roots of vascular plants form mycorrhizae with fungi, not lichens, so that option confuses two different symbiotic associations.
