What is an organism that lives in or on a host cell?
A parasite is an organism that lives in or on a host cell. Parasites rely on the host for nutrients and can cause harm to the host they live in. Examples include Plasmodium, the parasite that causes malaria, and tapeworms.
What 2 hosts do a parasite need?
A parasite typically requires two hosts: the definitive host and the intermediate host. The definitive host is where the parasite reaches maturity and reproduces, while the intermediate host is where the parasite undergoes development or larval stages. This two-host life cycle allows the parasite to complete its life cycle and spread effectively. Examples include the malaria parasite, which uses humans as the definitive host and mosquitoes as the intermediate host.
What does the word host cell mean?
A host cell is a cell that is infected or invaded by a virus, bacteria, or parasite that uses the host's cellular machinery to replicate or survive. In the context of parasitology, it refers to the cell that a parasite lives in or feeds on.
How long must a malaria parasite grow in its host before infection can be spread to human being?
It takes about 8-30 days for the malaria parasite to complete its growth in the mosquito before it is capable of infecting a human host. This period allows the parasite to develop in the mosquito's salivary glands, where it can be transmitted to humans when the mosquito bites.
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.

A parasite is an organism that lives in or on a host cell. Parasites rely on the host for nutrients and can cause harm to the host they live in. Examples include Plasmodium, the parasite that causes malaria, and tapeworms.
Where does the mosquito carry the malaria parasite?
it carries it to the host
What group does malaria parasite belong?
Malaria parasite is a protozoan.
Is the parasite that causes malaria a type of euglenoid?
No, the parasite that causes malaria is not a type of euglenoid. The parasite that causes malaria is a type of protozoan.

Does a parasite give humans chickenpox or malaria?
Chickenpox is caused by a virus, and malaria is caused by a parasite.
What is an example of a dependent protist?
An example of a dependent protist is an apicomplexan parasite like Plasmodium, the causative agent of malaria. This protist depends on a host organism for survival and reproduction, and cannot live independently outside of a host cell.
What is malaria in biology?
Malaria is a protist that is a deadly parasite.
Which test is used to detect malaria?
Antigen test for malaria parasite and peripheral smear for malarial parasite.
How does injecting the anticoagulant help spread malaria?
Injecting an anticoagulant can facilitate the spread of malaria by enhancing the survival and movement of the malaria parasite within the host's bloodstream. Anticoagulants prevent blood clotting, allowing the parasite to circulate more freely and infect red blood cells. This can lead to an increased severity of the infection and a higher likelihood of transmission to mosquitoes when they bite the infected host. Consequently, the overall spread of malaria in the population can be exacerbated.
Do individuals who are heterozygous for sickle-cell anemia have a greater resistance to malaria?
Yes, individuals who are heterozygous for sickle-cell anemia have a greater resistance to malaria due to the presence of the sickle cell trait which makes it more difficult for the malaria parasite to survive in the red blood cells.
