FAQs on Viruses, Viroids & Lichens Video Lecture - Biology Class 11 - NEET
| 1. What are viruses and how do they differ from viroids? |  |
Viruses are infectious agents that can only replicate inside the cells of living organisms. They consist of genetic material (either DNA or RNA) surrounded by a protein coat. Viroids, on the other hand, are much simpler infectious agents that consist only of a short piece of RNA. Unlike viruses, viroids do not have a protein coat.
| 2. Can lichens cause diseases in humans? | |
No, lichens do not cause diseases in humans. Lichens are a symbiotic relationship between a fungus and an alga or a cyanobacterium. They are typically found in diverse environments, such as rocks, trees, and soil, and play important ecological roles. While some lichens produce secondary metabolites that have medicinal properties, they do not pose a threat to human health.
| 3. How do viruses and viroids reproduce? | |
Viruses reproduce by infecting host cells and using the host's cellular machinery to replicate their genetic material and produce new virus particles. They can infect a variety of organisms, including plants, animals, and bacteria. Viroids, on the other hand, do not have the ability to infect host cells directly. They rely on the host's cellular machinery to copy their own RNA, leading to the production of more viroids.
| 4. Are there any similarities between viruses and lichens? | |
No, viruses and lichens are very different entities. Viruses are infectious agents that require a host to replicate, while lichens are a symbiotic relationship between a fungus and an alga or a cyanobacterium. Viruses are much smaller in size and simpler in structure compared to lichens. Additionally, viruses can infect a wide range of organisms, while lichens are primarily found in terrestrial environments.
| 5. Can lichens be used as indicators of environmental pollution? | |
Yes, lichens can be used as bioindicators of environmental pollution. They are highly sensitive to changes in air quality and are known to accumulate heavy metals and other pollutants from the environment. By studying the presence and health of lichens in a specific area, scientists can assess the level of pollution and its impact on the environment. This makes lichens valuable tools for monitoring and managing environmental pollution.
