Question

The sporozoa are all internal _____ that typically have an infective cyst stage in their life cycle. An example of sporozoa is the genus ______ which causes malaria.
A. Ciliates, Plasmodium
B. Flagellates, Plasmodium
C. Parasites, Plasmodium
D. Parasites, Trypanosome

Answer 1

Hint:-Malaria is the severe disease infected by Anopheles mosquito. It carries plasmodium parasites. Malaria parasite completes its life cycle in two hosts one is human where it reproduces asexually and other is the mosquito which carries infective stage of the plasmodium. The infective stage of plasmodium is the sporozoite stage. Sporozoa is the type of parasite. Plasmodium is the genus of unicellular eukaryotes that act as parasites for many vertebrates.

Complete answer:
Malaria is a very harmful disease as it causes death of the individual. Transmission takes place through the bite of an infected Anopheles mosquito. Plasmodium parasites are carried by infected mosquitoes. The parasite is released into the blood when the mosquito bites. Plasmodium needs two hosts to complete its life cycle.
Human host: In this asexual reproduction of parasite occur. When the parasites enter into the body they travel through the liver, and enter into RBC to form gametocytes. Gametocytes enter into the bloodstream when RBC ruptures. It can cause various symptoms, life fever and chills.
Mosquito: Gametocytes reproduce sexually into the gut of a mosquito when it bites the infected human and mature there to form an infective stage known as sporozoites. Sporozoites mix with saliva of mosquito and when the same mosquito bites any human sporozoites enter into it and migrate to the liver where they mature to schizonts and merozoites released and infect RBC.
This cycle continues in the same manner if proper prevention and treatment is not taken.
Sporozoa is the subphylum of protozoa. Plasmodiums that are known as parasitic protozoan are the causative creatures of intestinal sickness.
The sporozoa are all internal parasites that typically have an infective cyst stage in their life cycle. An example of sporozoa is the genus plasmodium which causes malaria.
The correct answer is option C.

Note:- Malaria is infectious disease water borne disease. It causes symptoms like fever, tiredness, vomiting, and headaches. It can also cause seizures, coma, or even cause death. Antigen detection test is done to diagnose it. Malaria can be prevented by medication, mosquito elimination, and prevention of bites. In the 21st century, drug resistance poses a problem in malaria treatment. Malaria is not just harmful for human life but it can also cause economic impacts in society.
