They are called obligate intracellular parasites because they must use a host cell's amino acids to synthesize proteins, metabolic enzymes and pathways to obtain energy, ribosomes to synthesize proteins, and nucleotides for transcription and replication. In other words, they need to use just about everything from a host cell in order to survive.

∙ 12y agovirus are connecting link between living and non-living. As they possess the capabilty of multiplying themselves which is the general propertiy of living beings but they can not multiply all alone or we can say that they need a living cell as a host in which they can take over the DNA replication machinery of the host and start dividing its genetic material and protein coat so that's why viruses are obligatory intracellular parasite.

∙ 13y agoBecause, a virus doesn't fit any living category. The way it works is it goes to a cell and injects its DNA into it to make more viruses. Scientists have wondered whether to classify a virus as biotic or abiotic for a long time (living or non living). So I guess that they made a category that fits the virus' traits.

∙ 13y agoviruses are infectious agents that cannot produce their own energy. therefore, they need a host cell to produce energy, synthesize and assemble new virus particles.

Is there a life that doesn't need oxygen?
Yes. There are organisms called anaerobic bacteria which do not need oxygen. To some organisms, called obligate anaerobes, oxygen is actually toxic. The first living things on Earth were obligate anaerobes.
What is the fluid component of the cytoplasm called?
Cytosol!!!
How does the skin protect you and what does it protect you against?
Skin protects the inside of the body from bacteria. If it weren't for skin, we would get infections way too easily and certainly would not be able to survive. Not only just bacteria, but from viruses, parasites, and fungi too. A substance called melanin protects your skin from burns.
Do viruses have a protein coat?
no
Determine how some viruses might be helpful?
they can be made into vaccines against themselves. Additionally, virsuses that attack bacteria, called bacteriophages, may someday be used to treat bacteria infections. There has also be research into using viruses to kill harmful insects.
What kind of pathogenic organism live inside cells?
These are called intracellular parasites. All viruses are in this group. Obligate bacteria types include Rickettisae and Chlamydia. Also there are a few that are considered to be non-obligate:Mycobacterium and Brucella.
Is the reason viruses are called obligatory intracellular parasites because they require a cell host to replicate?
yes.
How do you use the word intracellular in a sentence?
Microparasite that are capable of growing and reproducing inside the cells of a host are called intracellular parasites.
Why are viruses called obligate parasite?
Because they absolutely require living host cells in order to multiply
What is one reason that a virus is not considered living?
According to many scientific literature, all living organisms should be able to reproduce.Viruses do not reproduce. Instead, they inject their genetic material into another cell. This process is called pilus.
Which microbes do not need to multiply inside of living cells?
They are called parasites. Some bacteria, fungi etc
Bacteria that only grows with the absence of oxygen?
Bacteria that can ONLY grow in the absence of oxygen are called obligate anaerobes.
Bacteria that are killed by oxygen are called obligate?
anaerobes
What is a pathogen that grows inside a cell called?
Intracellular.
A bacterium that can enter the structure of a host cell is called?
intracellular.
What are the medicinal properties of mirabilis jalapa?
kill viruses, bacteria, fungi, and parasites. This plant has many active compounds like triterpenes, proteins, flavonoids, alkaloids, and steroids. A group of amino acid-based proteins called MAPs protect against plant viruses.
What are bacteria that can't live without oxygen called?
Obligate aerobes.
