The sporozoites that cause infection, when a female Anopheles mosquito bites a person are formed ina)Liver of personb)RBCs of mosquitoc)Salivary glands of mosquitod)Intestine of mosquitoCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

When a infected  female anopheles bites a person then the sporozoites which are present in the salivary gland of the mosquito reach the liver through blood then sporozoites reproduces asexually in the liver cells form spores and release in blood and then the sporozoites reproduces asexually in the RBC and form merozoites or male gametocytes and when the female anopheles bites infected person  the male gametocytes reach the intestine of female anopheles and fertilisation take place and sporozoites formed and it runs to the salivary gland of female anopheles.so correct answer is absolutely is in the intestine

Answer

Answer

Fertilisation occurs in intestine of female Anopheles mosquito after this sporozoites escape from intestine and migrate to the mosquito salivary glands.

Answer

P. vivax undergo reproduction in the gut(intestine) of the female Anopheles mosquito to form sporozoites. These are then stored in the salivary glands of the mosquito. When this mosquito bites a human being, the sporozoites are transferred into his/her body and causes the deadly malarial disease.

Answer

(d)
The female Anopheles mosquito when bites an infected person,the malarial parasites enter into the mosquito's body and undergo further development to form sporozoites in the intestine that finally move to salivary gland of the insect.

Answer

Fertilization and development takes place in stomach of the mosquito or gut of mosquito.the mature infective stages are the sporozoites which are formed in the intestine .later these escape and migrate to the mosquitos salivary glands.if u r not clear with it refer NCERT class 12 text pg.148

Answer

When a female anopheles mosquito bites a person, haemozoin is released into their body which attacks livers cells then RBCs,some of it gets differentiated to form gametocytes(male and female both) they do not fertilise within human but when another female anopheles mosquito bite that infected person this gametocytes are taken into their body which fuses in the mosquito gut(alimentary canal) and later is stored in their salivary gland.

Answer

Yaa...see most infectious stage sporozoit which is formed in the alimentary canal of mosquitoes (.. mostly in intestine).. stored in salivary glands of mosquitoes..and leads to the rupture of rbc and hepatocytes( liver cells)

Answer

Sporozoites Formation and Transmission

Sporozoites are the infective stage of the protozoan parasite, Plasmodium, which causes malaria. These sporozoites are formed in the intestine of the female Anopheles mosquito and are transmitted to humans when the mosquito feeds on the blood of an infected person.

Intestine of Mosquito as Sporozoites Formation Site

When a mosquito bites an infected person, it ingests gametocytes (the sexual stage of the Plasmodium parasite) along with the blood. These gametocytes undergo sexual reproduction in the mosquito's midgut, resulting in the formation of zygotes. The zygotes develop into ookinetes, which then penetrate the midgut wall and form oocysts on the outer surface of the mosquito's midgut. These oocysts grow and divide, producing thousands of sporozoites.

Sporozoites' Transmission to Human Body

After about 10-14 days, the oocysts rupture, releasing the sporozoites into the mosquito's body cavity. The sporozoites then migrate to the mosquito's salivary glands, where they are stored until the mosquito feeds again. When the mosquito bites another person, the sporozoites are injected along with the mosquito's saliva into the person's bloodstream. The sporozoites then travel to the liver, where they infect hepatocytes and begin the asexual stage of the parasite's life cycle.

Conclusion

In conclusion, sporozoites that cause malaria infection are formed in the intestine of the female Anopheles mosquito. After undergoing sexual reproduction, the zygotes develop into ookinetes, which penetrate the midgut wall and form oocysts. These oocysts release thousands of sporozoites, which migrate to the mosquito's salivary glands and are transmitted to humans during a mosquito bite.

Answer

When it bites us sporozite reaches our liver and from there it reaches our RBC and damage it.

Answer

Option D : Intestine of mosquito

Answer

Female anopheles sucks gametocyte stage of plasmodium from infected humans blood. then the male and female gametocyte fuse inside anopheles body in the intestine region. this is known as fertilisation and it occurs in the intestine of the mosquito. then these fertilised zygotes develop into sporozoites when sporozoite become mature they move to salivary gland of the mosquito.now when this mosquito bites a healthy human sporozoites are injected in him and he becomes infected. so by this, we see, sporozoites were born in the intestine of the mosquito.

Answer

At the intestine only the sporozoites are formed but are stored after in salivary gland

Answer

Read the diagram from NCERT carefully.
some tricks
Meiosis division /Exflagellation/Okinete formation /Asexual and sexual reproduction /Gametogenesis/primary host....present in mosquito
Singnet stage/secondry host /Asexual reproduction /sporozite formation ..present in human

Answer

After  completion of mitotic division in liver cell, it goes to gut of mosquito where  meiotic division  complete  and formed sporozoit and then goes  to salivary gland

Answer

According to NCERT sporozoites are formed in the gut of the mosquito

Answer

Sporozoites formed in mosquito intestine

Answer

Correct answer is option.d. intestine of mosquito
