In bacterial viruses, the protein coat remains outside the cell and only the viral genome is injected into the cell. In animal viruses, the virus attaches to specific receptors on the plasma membrane and the whole virus is taken in by endocytosis (pinocytosis or phagocytosis). The viral envelope (if present) is stripped off inside the cell, and the separation of the viral genome from the protein coat then takes place. Not all infections of animal host cells result in lysis of the cell (as in the lytic cycle of bacteriophages). In the case of enveloped animal viruses, the viruses are released by a budding process. The process is slow and the host cell may remain alive and continue to release viruses over a long period of time. In some cases the virus may become dormant (though remaining infectious) inside the host cell, appearing spontaneously at a later time. (Unlike temperate bacteriophages that integrate their DNA into the genome of the host cell as provirus, animal viruses do not usually integrate into the animal genome during the latent stage.) Finally, some animal viruses may cause transformation of host cells to the cancerous state.
--Differences between bacteriophages and viruses that infect eukaryotic cells
Yes, viruses are smaller than eukaryotic cells.
Viruses, prokaryotic cells, eukaryotic cells. Viruses are the simplest, consisting of genetic material surrounded by a protein coat. Prokaryotic cells are more complex, with no membrane-bound organelles and a simpler structure than eukaryotic cells, which are the most complex with membrane-bound organelles and a nucleus.
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.
Viruses are technically not alive, and so are not classified as cells. Only cells are classified as prokaryotic or eukaryotic. For cells, prokaryotic means it has no nucleus while eukaryotic means it has a nucleus.
Viruses are infectious agents that can only replicate and survive by invading host cells and hijacking their cellular machinery. Once inside a host cell, viruses use the cell's resources to produce more viral particles, which can then go on to infect other cells. This process ultimately leads to the destruction of the host cell as new viruses are released to infect additional cells.

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.

somehow
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.
Highly specific
Viruses are different from eukaryotic cells in structure and replication. Viruses are smaller and simpler, consisting of genetic material surrounded by a protein coat. They cannot replicate on their own and rely on host cells to reproduce. Eukaryotic cells, on the other hand, are larger and more complex, with a nucleus and organelles. They can replicate independently through mitosis or meiosis.
