State the mode of a sexual reproduction in plasmodium .
Sexual reproduction takes place in Plasmodim vivax. After the erythrocytic phase some merozoites on entering the RBC develop into sexually differentiating forms called gamatocytes. These are two types male gamatocytes and female gametocytes. When female anopheles mosquito bites a person suffering from malaria these gamatocytes enter into the crop of the mosquito. In malegamatocyte the nucleus divide into 8 daughter nuclei and 8 flagellated processes appear on the cytoplasm. Each nuclear bit passes into each of these cytoplasmic extentions and forms a male gamete.this process is called ex flagellation. Female gamatocyte undergo maturation to form female gamete. The nucleus moves towards pheriphery and cytoplasm forms a projection at that point.this projection is called fertilisation cone During.fertilization, the male gamete keep on actively lashing movement. One of these comes in contact with the fertilisation cone of female gamete and enter into it.The pronucleus of male gamete fuses with female gamete.as fusing gamates are dissimilar in form this fusion is described as anisogamy. This result's in formation of spherical zygote.
