MALARIA PARASITE REPRODUCTION IN HUMANS
mosquito carrying plasmodium
(parasite) bites human releasing
plasmodium
into their
blood stream
plasmodium
makes it way into the
liver cells
where it
reproduces asexually
by
mitosis
producing
diploid cells
Liver cells
eventually
burst
and
diploid cells
make there way into the
red blood cells
where they continue to
reproduce asexually
MALARIA PARASITE REPRODUCTION IN MOSQUITOES:
another mosquito with
plasmodium
in
saliva
bites human with
malaria
temperature
difference between
saliva
and
human body
triggers
MEIOSIS
red blood cells bust inside mosquito
and
plasmodium fuses
with the
plasmodium inside
saliva
forms a new variant of malaria
which is injected into the next human the mosquito bites
