Class 11 into major groups; Lichens, Viruses and Viroids

Class 11 into major groups; Lichens, Viruses and Viroids- Lichens, viruses, and viroids are three distinct biological entities, each belonging to different groups and exhibiting unique characteristics. Here’s a brief overview of each:

1. Lichens:
   • Classification: Lichens are not a single organism but a mutualistic association between a fungus and a photosynthetic partner, typically an alga or a cyanobacterium.
   • Components: The fungal partner provides a protective structure, while the photosynthetic partner contributes to food production through photosynthesis.
   • Habitat: Lichens are commonly found in various environments, including rocks, trees, and soil.
2. Viruses:
   • Classification: Viruses are not classified within any of the traditional biological kingdoms. They are considered obligate intracellular parasites and are composed of genetic material (either DNA or RNA) surrounded by a protein coat (capsid).
   • Structure: Viruses lack cellular structure and cannot carry out metabolic processes on their own. They rely on host cells to reproduce.
   • Replication: Viruses infect host cells, hijack the cellular machinery to replicate, and often cause diseases in animals, plants, and bacteria.
3. Viroids:
   • Classification: Viroids are even simpler than viruses and are classified as subviral agents. They consist solely of a small, circular RNA molecule without a protein coat.
   • Function: Viroids cause diseases in plants by interfering with the host’s cellular processes. They can affect the growth and development of the infected plant.
   • Transmission: Viroids are typically transmitted through plant-to-plant contact or via agricultural practices such as the use of contaminated tools.

In summary, lichens represent a symbiotic relationship between a fungus and a photosynthetic partner, viruses are genetic entities that require host cells for replication, and viroids are small infectious agents composed of RNA that cause diseases in plants. Each of these groups plays a unique role in the biological world and has distinct characteristics.
