Motile zygote of Plasmodium occurs in
Show Hint
Malaria is a mosquito-borne infectious disease that affects humans and other animals and is caused by Plasmodium species. In the female Anopheles mosquito, gametocytes are taken up with the blood and mature in the mosquito gut. The male and female gametocytes fuse and form an ookinete—a fertilized, motile zygote. Ookinetes develop into new sporozoites that migrate to the insect's salivary glands, ready to infect a new vertebrate host.
- Human RBCs
- Human Liver
- Gut of female Anopheles
- Salivary glands of Anopheles
The Correct Option is C
Solution and Explanation
Motile zygote of Plasmodium occurs in Gut of female Anopheles.
Malaria is a mosquito-borne infectious disease caused by Plasmodium species. in humans and is transmitted through the bite of an infected female Anopheles mosquito. When female Anopheles sucks the blood of an infected human it takes up gametocytes (sexual stages of parasite) with blood meal. The gametocytes come out of the RBCs into the lumen (cavity) of the stomach of the mosquito. In the stomach, the male gametocyte divides and forms 6 to 8 long, motile, whip-like microgametes (male gametes). The female gametocyte does not divide but undergoes a process of 1 maturation to become the macrogamete (female gamete), i A microgamete penetrates a macrogamete, and fertilization | (syngamy) takes place, resulting in the formation of a zygote. The zygote elongates and becomes a worm-like motile organism called ookinete. Ookinete further changes into sporozoites (mature infective stage of Plasmodium).
Therefore, the correct answer is option C.

Common Diseases in Human Beings
Any adverse variation from an organism's normal structural or functional condition is usually associated with specific signs and symptoms and distinct from physical injury.
- Acute Disease
A few diseases appear out of nowhere and persist only a few days. Acute diseases, such as the common cold, are examples of them. Acute diseases frequently become chronic if they are not treated.
Acute diseases include strep throat, fractured bones, appendicitis, influenza, pneumonia, and others.
- Symptoms and Treatments
Acute diseases develop quickly and are accompanied by unique symptoms that necessitate immediate or short-term treatment and improve once treated. Acute illnesses, such as the common cold, can sometimes go away on their own.
- Chronic Diseases
Chronic diseases are illnesses that develop over time and endure for a long time or even a lifetime. Chronic disease is defined as a disease that lasts more than three years. The symptoms are relatively modest at first.
