1. What kind of microorganisms live in this lake?

2. We should know about the members of ;
KINGDOM
PROTISTA

3. LET’S MEET PROTISTS...
They are unicellular & very simple multicellular organisms.
All are eukaryotes. Because they have distinct membrane enclosed nuclei & organels...
They live in places e.g. fresh water ponds, streams, sea and the soil. Some parasitic forms live within bodies of other organisms
They may reproduce sexually or asexually.

4. HOW DO THEY MOVE ? Many protists have a special structure to move;
# Flagella kamçı
# Cilia sil
# False feet yalancı ayak
# Some non-motile...hareketsiz

5. HOW DO THEY GET THEİR FOOD?
# Ways of obtaining food are so different
Some are autotrophs & produce their own food [ EUGLENA / ALGAE ]
Some are heterotrophs...
[AMOEBA, PARAMECIUM, SLIME MOLD]
3. Some are parasites.

6. TYPES OF PROTISTA ANIMAL- LIKE PROTISTS :
# Amoebas kökayaklılar
# Flagellates kamçılılar
# Ciliates silliler
# Sporozoans sporlular
PLANT - LIKE PROTISTS; ALGAE
FUNGUS – LIKE PROTISTS;
(Slime molds & water molds)

7. are present. Ameobas divide into 2 new cells by binary fussion.
1. ANIMAL – LIKE PROTISTS
a. AMOEBAS amoeba
The extention of the cell membrane and cytoplasm is known as pseudopodium.
(false feet). This helps them move and capture food. Contractile & food vacuole
are present. Ameobas divide into 2 new cells by binary fussion.

8. b. FLAGELLATES (euglena) They live in fresh water
ponds. They have flagella
to move. As euglena has
chloroplast, it is autotrophic.
They have food & contractile
vacuole. They are divided into
2 new cells by binary fission.

9. c. CILIATES; (paramecium)
Ciliates have small hairlike projections called cilia for moving. Food vacuole
forms around the incoming food.After food is digested, wastes are sent into
the water. They are unique in having 2 types of nuclei;
# single macronucleus for everyday activities
# micronucleus for sexual reproduction

10. d. SPOROZOANS; They are non–motile. They reproduce by spores. They’re
parasitic.Plasmodium cause malaria.NO contractile vacuole
