Plasmolysis is a phenomenon observed in plant cells when they lose water and the cell membrane pulls away from the cell wall. This process typically occurs in a hypertonic solution, where the concentration of solutes outside the cell is higher than inside. As a result, water exits the cell by osmosiRead more
Plasmolysis is a phenomenon observed in plant cells when they lose water and the cell membrane pulls away from the cell wall. This process typically occurs in a hypertonic solution, where the concentration of solutes outside the cell is higher than inside. As a result, water exits the cell by osmosis, causing the cell’s central vacuole to shrink and the cytoplasm and cell membrane to contract.
Key points about plasmolysis:
In summary, plasmolysis is an important process in understanding how plant cells respond to osmotic stress and helps illustrate the effects of different solute concentrations on cell integrity.

Two Main Components of a Typical Virus
Introduction
Viruses are unique infectious agents that differ from other microorganisms such as bacteria and fungi. They cannot reproduce independently and rely on the host cell’s machinery to replicate. Despite their simplicity, viruses have a structured organization with two primary components that are crucial for their function.
1. Genetic Material
2. Protein Coat (Capsid)
Conclusion
The two main components of a typical virus are:
Understanding these components is essential for developing antiviral therapies and vaccines. For UPSC Mains aspirants, knowledge of viral structure and function is important for answering questions related to microbiology, infectious diseases, and public health.
