Viruses need a host cell to replicate and multiply because they lack the cellular machinery for these processes. By hijacking the host cell's machinery, viruses can produce more viral particles and continue their infectious cycle. This allows viruses to thrive and spread within a host organism.

What type of organism requires a host cell?
Viruses require a host cell to replicate and reproduce. They inject their genetic material into the host cell where it instructs the cell to make new virus particles.
What are the differences between a virus and a parasite?
Viruses are infectious agents that require a host cell to replicate, while parasites are organisms that live in or on another organism and derive nutrients at the host's expense. Viruses are much smaller and simpler than parasites, and they replicate by hijacking the host cell's machinery. Parasites can be multicellular organisms like worms or single-celled organisms like protozoa.
Is a virus a parasite?
Yes, a virus is considered a parasite because it depends on a host cell to replicate and survive. Viruses cannot replicate or carry out metabolic functions without a host cell, making them parasitic in nature.
What do viruses need to reporduce?
Viruses need a host cell to reproduce. Once they have infected a host cell, they use the cell’s machinery to make copies of themselves. This process eventually leads to the host cell bursting open and releasing new viruses to infect other cells.
Can a virus live outside a cell?
No
What type of organism requires a host cell?
Viruses require a host cell to replicate and reproduce. They inject their genetic material into the host cell where it instructs the cell to make new virus particles.
What is acellular obligatory parasite?
An acellular obligatory parasite is a type of parasite that lacks cellular structure and relies on a host cell's machinery for survival and reproduction. Examples include viruses, viroids, and prions. These parasites cannot replicate or carry out metabolic functions independent of a host cell.
Is a grasshopper a parasite or host?
Both. They eat plants, so they are a parasite. They can be infected with viruses, so they can be a host too.
Are viruses parasitic?
Yes because all the viruses uses host cell mechanisms to reproduce and then at the end of the reproduction process it destroy the host cell.Therefore there is no non-parasitic viruses.All viruses are parasitic.
How does a herpes virus get energy?
Like other viruses, herpes is an obligate intracellular parasite. It gets its energy from the host cell's ATP.
What are the differences between a virus and a parasite?
Viruses are infectious agents that require a host cell to replicate, while parasites are organisms that live in or on another organism and derive nutrients at the host's expense. Viruses are much smaller and simpler than parasites, and they replicate by hijacking the host cell's machinery. Parasites can be multicellular organisms like worms or single-celled organisms like protozoa.
What is the name for the virus that takes over the host cell?
That's pretty much how all viruses work...
Do Most DNA viruses multiply in the host cell's cell membrane?
No, DNA viruses multiply in the host cell's nucleus, while most RNA viruses multiply in the host cell's cytoplasm
Viruses make the host cell produce new viruses which kills th host cell?
Yes, viruses hijack the host cell's machinery to replicate themselves, eventually causing the cell to burst and release new viruses. This process, known as lysis, results in the death of the host cell.
What is the difference between obligate and facultative parasites?
Obligate parasites require a host to complete their life cycle and cannot survive without one. Facultative parasites can live either independently or as parasites depending on the environment and conditions.
How is a virus cause a disease in a host?
a virus can ony reproduce inside a living cell that surves as a host. A Host is living thing that a virus or parasite lives on or in . Using a host's cell as a tiny factory , the virus forces the host to make viruses rather than healthy new cells.
Why does viruses have parasites?
viruses are considered parasites (obligate parasites) because they cannot exist on their own. they need the host cell's machinery to reproduce so they cannot "survive" (technically not living) outside the cell.
