Question

Schizont stage of Plasmodium occurs in human cells
A) Erythrocytes
B) Liver cells
C) Erythrocytes and liver cells
D) Erythrocytes, liver cells and spleen cells

Answer 1

Plasmodium is a genus of unicellular eukaryotes that are obligate vertebrate and insect parasites. Plasmodium species' life cycles include growth in a blood-feeding insect host, which then injects parasites into a vertebrate host during a blood meal.

Complete answer:
Plasmodium is a genus of obligate parasitic unicellular eukaryotes that live in vertebrates and insects. Plasmodium species have life cycles that include development in a blood-feeding insect host before injecting parasites into a vertebrate host during a blood meal.

Female Anopheles mosquitoes, also known as "night-biting" mosquitoes because they strike most often between dusk and dawn, transmit the plasmodium parasite. If a mosquito bites a person who is already infected with malaria, the mosquito may become infected as well and spread the parasite to other people.

Plasmodium schizont is found in human erythrocytes and liver cells. The sporozoites circulate in the human blood for about half an hour before entering the liver cell. The sporozoites are removed from the bloodstream by the liver's kupffer cells, which destroy many of the species. However, some sporozoites avoid destruction and join the hepatocytes, where they take up residence.

The schizont stage of Plasmodium occurs in human cells in Erythrocytes so, option A is the correct answer.

Note: Plasmodium parasites are carried by infected mosquitoes. The parasite is released into your bloodstream when this mosquito bites you. While within the body, the parasites migrate to the liver, where they grow. The mature parasites invade the bloodstream and begin to infect red blood cells after a few days.
