Question

Identify the sequential life stages of Plasmodium in mosquito
A. Sporozoites  
B. Zygote  
C. Oocyst  
D. Sporocyst  
E. Sporoblast  

• A. A,B,C,D,E
• B. B,D,A,C,E
• C. D,B,E,A,C
• D. B,C,D,E,A

Hint:

The mosquito is essential in the transmission of *Plasmodium* to humans. The sporozoites are the infective stage, and they travel to the liver, where they multiply before moving on to the blood to cause malaria.

Answer 1

The Correct Option is D

The life cycle of Plasmodium in the mosquito consists of the following stages:

1. Sporozoites (A): These are the infectious form of the parasite that are injected into the mosquito's bloodstream during a bite. They travel to the liver and start multiplying.
2. Zygote (B): After fertilization inside the mosquito's gut, the zygote forms and matures into the oocyst.
3. Oocyst (C): The zygote develops into the oocyst, which is a cyst-like structure in the gut wall of the mosquito, where further reproduction takes place.
4. Sporocyst (D): Inside the oocyst, sporozoites are produced, which move to the salivary glands of the mosquito.
5. Sporoblast (E): This is the last stage before sporozoites are ready to be transmitted to a new host during the next mosquito bite.

Thus, the correct sequential order is: B → C → D → E → A.

Hence, the correct option is Option (4).
