LIFECYCLE OF PLASMODIUM IN MOSQUITO

PLASMODIUM LIFECYCLE IN MOSQUITO (CYCLE OF ROSS);
1.After repeated erythrocytic lifecycles in man the merozoite become inactive and transformed into gametocytes.
2.There are two types of gametocytes ,a)Macrogametocytes
b)Microgametocytes
3.Macrogametocytes are called female gametocytes and Microgametocytes are called male gametocytes.
4.The further development of the gametocytes needs female anopheles mosquito.
5.When the female anopheles mosquito bites a malaria patient the male and female gametocytes enter into the crop of mosquito
6.Male gametocytes develop into male gametes and female gametocytes into female gametes.
7.The male and female gametes are fused to form a zygote
8.Intially the zygote is stationary later it becomes motile
9.The motile zygote is called ookinete
10.The ookinete enters into the crop wall of mosquito
11. In the crop wall it gets encysted
12.The encysted zygote is called oocyst
13.In oocyst it enlarges and undergoes multiplications
14.Due to multiplications sporoblasts are formed
15.The cyst containing sporoblasts is called sporocysts
16.Sporoblasts develop into sporozoites
17.Sporozoites released from sporocyst and reach salivary glands
18.When this mosquito with sporozoites in its salivary glands bites a man ,the sporozoites enter into man and life cycle stars in man
