Parasites that reproduce only in living cells, apart from viruses, include certain types of protozoa, such as Plasmodium species (which cause malaria) and Leishmania species. Additionally, some intracellular bacteria, like Chlamydia and Rickettsia, must replicate within host cells. These organisms rely on the host's cellular machinery for their reproduction and survival, making them obligate intracellular parasites.

How are viruses harmful to living cells?
Viruses can reproduce very quickly. When reproducing they enter a living cell and they inject their genetic material.
Viruses can reproduce only inside what?
host cells!
What is a characteristic of viruses?
Viruses are non-living entities that require a host cell to replicate. They contain genetic material (either DNA or RNA) surrounded by a protein coat. Viruses can cause a wide range of diseases in various organisms.
Why would viruses not grow on milk?
Viruses require living cells to replicate and grow. Milk does not contain living cells, so viruses cannot infect or reproduce in milk. Additionally, milk has natural defense mechanisms, such as enzymes and antibodies, that can inhibit the growth of viruses.
Why scientist believe that virus are not living organisms?
Well, honey, scientists don't believe viruses are living organisms because they lack the ability to carry out essential life processes on their own. They can't reproduce without hijacking a host cell, so they're more like freeloaders than independent living beings. It's like calling a computer virus a living thing just because it can mess up your day.
What are pathogens that need living cells in order to reproduce called?
Pathogens that need living cells in order to reproduce are called obligate intracellular parasites. These pathogens rely on a host cell's machinery to replicate and spread throughout the body. Examples include viruses and certain bacteria.
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.
Viruses depend on living things for what?
Viruses depend on living cells because they reproduce inside of them.
What two ways that viruses do not act like living things?
They don't have their own metabolism and they can't reproduce on their own, two reasons for which they are obligatory parasites. They have to infect other cells with metabolisms to reproduce.
Is some viruses are prokaryotes and some are eukaryotes?
Viruses are neither prokaryotes nor eukaryotes as they are not living cells and do not have cell structure. They are parasites of living cells.
What particles reproduce that are made up of nucleic acids proteins and sometimes lipids only infecting living cells?
Viruses are particles that reproduce by infecting living cells. They consist of nucleic acids, proteins, and sometimes lipids.
What is the big difference between viruses and bacteria?
Viruses are replication parasites that can do nothing until they take over a living cell. Bacteria are living cells.
How are viruses harmful to living cells?
Viruses can reproduce very quickly. When reproducing they enter a living cell and they inject their genetic material.
What is the difference between reproduction cycles of viruses and reproduction cycles of living things?
Viruses don't have their own metabolism so they simply can't reproduce without a cell. That's why they are obligatory parasites. Living cells, on the other hand, can channel some of their metabolic energy to reproduce themselves, without having to take over something else's metabolism to do so, like viruses invariably have to.
Viruses can reproduce only inside what?
host cells!
What is a characteristic of viruses?
Viruses are non-living entities that require a host cell to replicate. They contain genetic material (either DNA or RNA) surrounded by a protein coat. Viruses can cause a wide range of diseases in various organisms.
What separates viruses from living things?
Viruses lack the ability to carry out basic functions of living organisms, such as metabolism and reproduction, when they are outside a host cell. They also do not have the machinery to generate energy or produce proteins on their own. Viruses are considered obligate intracellular parasites because they rely on host cells to replicate.
