Question

The figure above shows the cross section of lichen. Can you identify which components are shown in green and blue?

• A. Blue: Fungus, Green: Algae
• B. Blue: Algae, Green: Fungus
• C. Blue: Bacteria, Green: Algae
• D. Blue: Algae, Green: Bacteria

Answer 1

The correct option is A

Blue: Fungus, Green: Algae

Lichens are not single organisms. They are made up of a fungus and algae in a symbiotic relationship. The algae produce food by photosynthesis while the fungus provides protection. Observe that the stringy hyphae of the fungus provide shelter to the green photosynthetic algae in the figure.
