Explanation:
Lichens are composite organisms made up of two or three different organisms, a fungus and an alga and/or a cyanobacterium. They are found in a wide variety of habitats including deserts, mountains, forests, and polar regions, and are known for their ability to survive in extreme environments.
However, lichens are very sensitive to air pollution, particularly sulfur dioxide and nitrogen oxides, which are emitted by burning fossil fuels. Acid rain, which is caused by these pollutants, can also damage lichens. Therefore, option A is the correct answer.
Let's take a look at the other options:
- Option B: This statement is incorrect. The algal component of lichens is called the photobiont, while the fungal component is called the mycobiont.
- Option C: This statement is incorrect. The fungal component of lichens is called the mycobiont, while the algal component is called the photobiont.
- Option D: This statement is incorrect. Lichens are actually very good pollution indicators, as they are very sensitive to air pollution and can be used to monitor air quality.

Explanation:
Lichens are composite organisms consisting of a fungus and a photosynthetic partner, usually either a green alga or a cyanobacterium. They are commonly found in areas with low levels of pollution as they are sensitive to changes in their environment. Here are some reasons why lichens do not grow in polluted areas:
- Lichens are sensitive to air pollution: Lichens absorb nutrients and water directly from the air. Any pollutants in the air can be absorbed by the lichen and affect its growth and survival. Lichens are particularly sensitive to sulfur dioxide, nitrogen oxides, and heavy metals, which are common air pollutants.
- Lichen growth reflects air quality: Since lichens are sensitive to air pollution, they are often used as indicators of air quality. The presence or absence of certain lichen species can indicate the level of pollution in an area.
- Lichens are slow-growing: Lichens grow very slowly, sometimes only a few millimeters per year. This means that they are unable to keep up with rapid changes in their environment, such as sudden increases in pollution levels.
- Lichens are adapted to specific environments: Different lichen species have different environmental requirements, such as humidity, light levels, and substrate type. Pollution can alter these environmental factors, making it difficult for some lichen species to survive.
Therefore, it is correct to say that lichens do not grow in polluted areas as they are sensitive to changes in their environment and are commonly used as indicators of air quality.
