Question:

Observe the given figure and answer the given question.

Where does the fertilization and development takes palce in the life cycle of Plasmodium?

Options:

Gut of mosquito

Salivary glands of mosquito

Human RBC

Human Liver Cells

Correct Answer:

Gut of mosquito

Explanation:

The correct answer is Option (1)- Gut of mosquito

The fertilization and development of Plasmodium, the parasite responsible for malaria, occur in the mosquito's gut. Therefore, the correct answer is gut of mosquito

In the mosquito's gut, sexual reproduction takes place, resulting in the formation of sporozoites. Mature infective stages ( sporozoites) escape from gut and migrate to the mosquito salivary gland which are then transmitted to humans when the mosquito bites. Once in the human host, Plasmodium undergoes a series of developmental stages, including the invasion of human red blood cells (RBCs), which is a critical part of the parasite's life cycle. However, the initial sexual reproduction occurs in the mosquito's gut.
