Lichens
Introduction:
Lichens are unique organisms that are formed by the symbiotic association between fungi and algae or cyanobacteria. They are found in various habitats, including rocks, trees, soil, and even in extreme environments such as deserts and polar regions. Lichens play important ecological roles and have diverse uses in human society.
Explanation:
The correct answer is option C, which states that lichens need a regular supply of water for their growth. This statement is not correct because lichens are well-known for their ability to survive in extreme environmental conditions, including those with limited water availability. Lichens can absorb water from the atmosphere through their thallus and can tolerate desiccation for extended periods.
Key Points:
- Lichens are called bio-indicators as they act as an indicator of air pollution. They are very sensitive to air pollution, especially sulfur dioxide, and can be used to assess the quality of air in a particular area. The presence or absence of certain lichen species can indicate the level of pollution in the environment.
- Some lichens are used in the manufacturing of perfumes. Certain lichen species produce aromatic compounds that are used as natural fragrances in the perfume industry. These compounds have unique scents and are highly valued for their natural origin.
- Lichenometry is a technique used to determine the age of exposed rock surfaces. This method utilizes the growth rate of lichens to estimate the age of rock formations. By measuring the size of lichens and their colonization patterns on rocks, scientists can infer the approximate age of the surface.
- Lichens have a remarkable ability to survive in harsh environments with limited water availability. They can withstand desiccation and resume their metabolic activity when water becomes available. This adaptation allows lichens to colonize diverse habitats, including arid regions and polar environments.
Conclusion:
Lichens are fascinating organisms that have unique characteristics and ecological importance. While they do not require a regular supply of water for their growth, they serve as bio-indicators of air pollution, have uses in the perfume industry, and can be used for age determination through lichenometry.
