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 the reason viruses are called obligatory intracellular parasites because they require a cell host to replicate?
yes.
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.
Why virus are called obligatory parasites?
They are obligate in the sense that they cannot replicate outside of a host cell. To make a copy of itself, a virus must first enter a cell (intracellular), hijack the machinations of said cell (parasitic behavior) and then copy itself.
What are characteristics of viruses?
viruses are obligate intracellular entities and are considered to be acellular
Why is it difficult to classify viruses into one of the 5 kingdoms of living organisms?
Viruses lack the characteristics of living organisms, such as cellular structure and metabolism, making it challenging to classify them within the traditional system of biological classification. Additionally, viruses are considered obligate intracellular parasites that can only replicate inside host cells, further complicating their classification within the existing kingdom system.
What kingdown do most plants and animals belong to when difficult to classify?
lichens, corals, viruses, corals, viruses and carnivourous plants are difficult to classify :)
What were rickettsiae and chlamydia once thought to be?
Rickettsiae and Chlamydia were once thought to be viruses due to their small size and intracellular lifestyle, but they are actually classified as bacteria. They are both obligate intracellular pathogens that require host cells to multiply.
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.
What are several things used to classify viruses?
Viruses can be labeled as RNA or DNA viruses and they can be said to have an envelope or to be "naked".
What is the name for the virus that takes over the host cell?
The virus that takes over a host cell is known as an obligate intracellular parasite. It relies on the host cell's machinery to replicate and produce more viral particles.
Why are viruses intracellular?
Viruses are intracellular because they need to hijack the cellular machinery of a host cell in order to replicate and produce more virus particles. They cannot replicate on their own and rely on host cells to multiply. Once inside a cell, a virus releases its genetic material and uses the host cell's resources to replicate.
