Answer:
Viruses depend on a host cell's machinery and metabolic processes for their reproduction.Once inside a cell, viruses can follow two paths: the lytic cycle, where they take over the cell's machinery to replicate and burst the cell, releasing new viral particles, or the lysogenic cycle, where they integrate their genetic material into the host cell's DNA, remaining dormant until triggered to enter the lytic cycle.Three human diseases caused by viruses are HIV/AIDS, influenza, and COVID-19.Viruses do not have the characteristics of living things; they are not composed of cells, cannot carry out metabolic processes, and do not grow or respond to stimuli.Viral reproduction differs from cell-based organisms in that viruses lack the cellular machinery and metabolic processes required for independent replication. Instead, they rely on host cells to reproduce.Unfortunately, I cannot provide a graphic organization through this text-based interface, but I can briefly describe the structural differences:Viruses are much smaller and simpler in structure than prokaryotic and eukaryotic cells.Viruses consist of genetic material (either DNA or RNA) encased in a protein coat (capsid).Prokaryotic cells (e.g., bacteria) have a cell wall, cell membrane, and cytoplasm. They may have flagella or pili.Eukaryotic cells (e.g., animal and plant cells) have a nucleus, organelles, a cell membrane, and cytoplasm. They are much larger and more complex than viruses.
