Which part of the tobacco plant is infected by Meloidogyne incognita ?...
Infectious stage of Plasmodium that enters the human body is Sporozoites.
Explanation:
Plasmodium is a protozoan parasite that causes malaria in humans. The life cycle of Plasmodium involves two hosts: mosquito and human. When an infected mosquito bites a human, it injects saliva containing the sporozoites of Plasmodium into the human body. These sporozoites enter the bloodstream and travel to the liver where they infect the hepatocytes. After a period of incubation, the sporozoites multiply asexually in the liver cells to form merozoites.
The merozoites are released into the bloodstream and infect the red blood cells (RBCs). Inside the RBCs, the merozoites multiply asexually to form more merozoites, which then burst the RBCs and release more merozoites into the bloodstream. This causes the symptoms of malaria, such as fever, chills, headache, and fatigue.
Thus, the infectious stage of Plasmodium that enters the human body is the sporozoites, which are injected into the human body by an infected mosquito.
