All given statements stand true with respect to Lichens, excepta)Absen...
Explanation:
Mycobiont partner of lichens is always heterotrophic:
- This statement is false because the mycobiont partner of lichens is actually a fungus, which is generally considered to be heterotrophic.
- The mycobiont provides structure and protection to the lichen, while the phycobiont (algal partner) provides photosynthetic products to the fungus.
- The relationship between the mycobiont and phycobiont is mutualistic, as both partners benefit from the association.
Abundance of lichens in any area indicates that the area is highly polluted with SO2:
- This statement is true as lichens are known to be sensitive to air pollution, particularly sulfur dioxide.
- High levels of SO2 in the air can inhibit the growth of lichens, so the presence of abundant lichens in an area with low levels of pollution indicates a healthier environment.
- Lichens are often used as bioindicators of air quality due to their sensitivity to pollutants.
Body of lichens is made up of phycobionts only:
- This statement is false because the body of lichens is actually a symbiotic structure composed of both fungal (mycobiont) and algal (phycobiont) components.
- The mycobiont provides the structure and protection, while the phycobiont provides the photosynthetic capabilities necessary for the lichen to survive.
- The combination of these two partners allows lichens to thrive in a variety of environments.
The algal component of lichen is known as mycobiont and fungal component as phycobiont:
- This statement is false as it incorrectly labels the fungal and algal components of lichens.
- The algal component of lichen is known as the phycobiont, while the fungal component is known as the mycobiont.
- The mycobiont and phycobiont work together in a symbiotic relationship to form the unique structure of lichens.

All given statements stand true with respect to Lichens, excepta)Absen...
(B) The correct answer is B: Mycobiont partner of lichens is always heterotrophic.
Here's the detailed explanation:
- Lichens are symbiotic organisms consisting of a fungus (mycobiont) and an alga or cyanobacterium (phycobiont).
- The mycobiont is the fungal partner in lichens and is typically heterotrophic, meaning it obtains organic carbon from the environment.
- The phycobiont, which can be an alga or a cyanobacterium, is autotrophic and provides the mycobiont with organic carbon through photosynthesis.
- This mutualistic relationship allows lichens to thrive in diverse environments by combining the strengths of both partners.
