PROTIST
Animal-like protist are often
called protozoan. Protozoan
comes from Latin word, that is
Protos means the first and zoon
means animal. So, protozoanmeans the first animal.

According to their
movement organ Protozoaare grouped into 4 phylum,
that is :1. Rhizopod Phylum
2. Ciliate Phylum3. Flagella Phylum
4. Sporozoan Phylum

FLAGELLATE PHYLUMFlagellates are cells with one or more whip-like organelles called flagella. Some cells in
animal may be flagella, like Euglena.Higher plants and fungi dont produce
flagella cells, but the closely related greenalgae.

Many protist take theform of single-calledflagellates. They arefound in most line ofeukaryotes.

The characteristic of flagellate :
1. Have one or more flagella(whip-like projection)
2.Include unicellular
3. Found in kingdom protist
4. life as parasite, or free life in sea
water and fresh water habitat.5. Heterotrophic protista
6. Have contractile vacuoles

The Reproduction of FlagellateReproduction of flagellates isdone asexually by self division incross section. Some flagellatesmake reproduction sexually. The
members of flagellate includeTrypanosoma,Trichomonas &Leishmania.

THE FUNCTION OF FLAGELLATE
In protist and microscopic animals,flagella are generally used for propulsion.
They may also used to create a current
that brings in food. In most eukaryotes,one or more flagella are located at or nearthe anterior of the cell.
Some flagellates, like Dinoflagellatesare important primary producers(photosynthesisers) in lakes and ocean.

SPOROZOAN PHYLUM
Sporozoans (PhylumApicomplexa) areparasitic protistansthat must live part ofthe time inside specificcells of host species.

All produce asporozoite stage that isvery often transmittedby insects. Malaria,caused by Plasmodium and transmitted bymosquitoes, is a seriousworldwide disease.

1. Adult sporozoans have nostructures for movement
2. Form spores3. Most are parasitic using one or
more hosts4. Immature sporozoans are calledsporozoites & live in body fluids of
hosts5. Have phases is the sporeformation
6.Have hases is the s ore

THE REPRODUCTION OFSPOROZOAN
There 2 kinds of Sporozoan
reproduction: Asexual reproduction that
forms spores Sexual reproduction that
forms gamet

Sporozoans reproduce by multiplefission, that is producing more than
2 individuals. Reproduction ofsporozoan examples is in
plasmodium forms a life cyclebetween asexual cycle and sexualcycle. The life cycle of plasmodiumis in Anopheles mosquito thatcontains a lot of sporozoid (asexual
spores)

Anopheles mosquito that
contains a lot of sporozoid(asexual spore) bites human. It
begin by entering it saliva intothe human body as
anticoagulant, and of coursethe human body containts a
lot of sporozoid.

Then the sporozoite in retuculum
endotelium (usually in the hepar)undergoes a cycle but does not
attack yet, after that thesporozoite enters the red blood
cell. In here sporozoite grows anddevidees to makes asexual
spores

The asexual spore can
reproduce again in red
blood sare or enter the
body of Anophelesmosquito which bites
(sucks bloods) the
human who sufferfrom maralia.
