What else can I help you with?
What is it called when a single cell ameba surrounds a particle of food?
This process is called phagocytosis. The ameba engulfs the food particle by extending its cell membrane around it, forming a food vacuole which contains the particle for digestion.
What is a microscopic particle that invades a cell and often destroys it?
virus
Influenza is unicellular or multicellular?
Influenza is not a cell, it is a respiratory disease caused by a type of viruses, called influenza viruses. Viruses are not cells, they are sub-microscopic organisms that are non-living and disease-causing in humans, animals, and plants as well as in some bacteria.
When a cell membrane surrounds a particle encloses it into a vesicle and brings the particle into the cell this is called?
The process is called phagocytosis, which means "cell eating".
A virus is made of DNA and?
A virus is a tiny bundle of genetic material - either DNA or RNA - carried in a shell called a viral coat, or capsid, which is made up of protein. Some viruses have an additional layer around this coat called an envelope. When a virus particle enters a cell and begins to reproduce itself, this is called a viral infection. The virus is usually very, very small compared to the size of a living cell. The information carried in the virus's DNA allows it to take over the operation of the cell, converting it to a factory to make more copies of itself. For example, the polio virus can make over one million copies of itself inside a single, infected human intestinal cell.
Microscopic particle that invades a cell and destroys it?
A virus is a microscopic particle that invades a cell, takes over its machinery to replicate, and ultimately destroys the cell as part of its life cycle.
What is a nonliving particle that invades a cell?
a virus
What is a particle with dna but no nucleus or cell wall?
A virus is a particle with DNA but no nucleus or cell wall.
Is a virus a cell?
There is a lot of debate over whether a virus is truly alive; however, in general, a single virus is generally referred to as a particle rather than a cell.
How do virus enter a particle cell?
it will enter from air
What is it called when a single cell ameba surrounds a particle of food?
This process is called phagocytosis. The ameba engulfs the food particle by extending its cell membrane around it, forming a food vacuole which contains the particle for digestion.
Is a virus a single cell?
no
A microscopic particle that invades a cell and often destroys it?
Virus
What is a microscopic particle that invades a cell and often destroys it?
virus
What is it called when a virus attached to host cell injects its nucleic acid into the host cell then makes more viruses?
Attachment, or adsorption, occurs between the virus and the host cell membrane. A hole forms in the cell membrane, then the virus particle or its genetic contents are released into the host cell, where viral reproduction may begin.
Can a virus be called alive?
Viruses has a charateristics of being alive but they are NOT since they are single-cell organisms.
What is virion?
A virion is a complete virus particle outside a host cell, consisting of genetic material (either DNA or RNA) surrounded by a protein coat known as a capsid. Virions are the infectious form of a virus that can transmit its genetic material to infect a host cell and replicate.
