Question

Identify the incorrect statement about lichens____.

• A. They show fungal and algal symbiotic relationship
• B. They grow very rapidly (2 cm per day)
• C. Some species are eaten by reindeers
• D. They are pollution indicators.

Answer 1

The correct option is B

They grow very rapidly (2 cm per day)

Lichens grow by extending their thallus outwards from either tips or edges. They grow very slowly. Rates of growth can vary from 0.5 mm per year to 500 mm per year. This slow growth rate equates with their long life.
