Why cant every virus infect every living cell?
Viruses can only infect specific cells that have the necessary receptors on their surface for the virus to attach to. Each virus is adapted to infect specific types of cells based on these interactions. This specificity limits the range of cells that a virus can successfully infect.
Are viruses able to infect all cell?
No, viruses cannot infect all cells; they are specific to certain host organisms and cell types. Each virus has a specific set of host cells it can infect, determined by the presence of compatible receptors on the cell surface and the virus's mechanisms for entering the cell. This specificity means that while some viruses can infect a wide range of species, others are restricted to a particular host or cell type.
Are viruses always larger than cells they infect?
No, viruses are generally much smaller than cells they infect. Viruses are considered to be submicroscopic in size and are typically measured in nanometers, while cells are much larger and can be seen with a microscope.
How many different kinds of cells can any given virus infect?
A given virus can infect a limited range of cell types, often specific to certain hosts or tissues. This specificity is largely determined by the virus's surface proteins, which must match receptors on the host cell's membrane. For example, some viruses may infect only certain types of animal cells, while others may target specific plant or bacterial cells. Overall, the diversity of cells a virus can infect varies widely between different viruses.
What is the part of the cell that viruses invade?
Viruses can infect animals, plants and bacteria, and the attachments vary. In animal viruses: Animal cells have a cell membrane. Viruses attach to certain proteins in that membrane. In plant viruses: Plants can also be infected with viruses. Since they have cell walls, viruses attach to those when infecting plants. In bacteriophages (viruses that infect bacteria): Special viruses called bacteriophages attach to the cell walls of bacteria by way of proteins.
Are viruses general or highly specific to the cells they can infect?
Highly specific
What are most viruses highly specific to the cells they infect?
somehow
Why cant every virus infect every living cell?

Why are most viruses highly specific to cells they infects?
viruses must bind precisely to proteins on the cell surface and than use a hosts genetic system, this is why most viruses are highly specific to the cells they infect
What did the first viruses do?
Infect cells.
What are viruses that infect bacteria called?
the virus that infects bacteria is bacteriophage
Are viruses always larger than cells they infect?
No, viruses are generally much smaller than cells they infect. Viruses are considered to be submicroscopic in size and are typically measured in nanometers, while cells are much larger and can be seen with a microscope.
What is the pathogen attacks specific cells and injects genetic materials?
Viruses attach specific cells and inject genetic material. There are viruses called bacteriophages that infect bacteria be injecting their genetic material into the bacterial host and invading their protein machinery. With animal viruses that infect animal cells (much larger than bacteria), the virus either injects genetic material OR gets into the cell whole before it begins to unleash its pathogenic effects
Why are viruses hard to cultivate in the laboratory?
Viruses are hard to cultivate in the laboratory because they require living host cells to replicate. This dependency on living cells makes it challenging to maintain viruses outside of a host organism. Additionally, viruses can be very specific about the types of cells they can infect, which further complicates the cultivation process.
How many different kinds of cells can any given virus infect?

Overall, the diversity of cells a virus can infect varies widely between different viruses.
What types of organisms does bacteriophage attack?
Bacteriophages are viruses that infect and replicate within bacteria. They do not infect human cells or other eukaryotic organisms. Bacteriophages are specific to infecting particular bacterial species or strains.
Can a virus infect any type of cell?
Yes.It infects fungi,plants,animals and bacterias
