KASARAGOD,KERALA

3.  ALL SINGLE CELLED
EUKARYOTES
WELL DEFINED NUCLEUS
 MEMBRANE BOUND CELL
ORGANELLES

4.  PRIMARILY AQUATIC
 FORMS A LINK WITH
PLANTS,ANIMALS AND FUNGI
 SOME HAVE FLAGELLA OR
CILLIA

5.  REPRODUCE ASEXUALLY
BY CELL FUSION
 SEXUALLY BY ZYGOTE
FORMATION

6. CHRYSOPHYTES
DINOFLAGELLATES
EUGLENOIDS
SLIME MOULDS
PROTOZOANS
PROTISTS ARE DIVIDED
INTO:

9.  DIATOMS OR GOLDEN
ALGAE(DESMIDS)
 IN FRESHWATER AND IN MARINE
 MICROSCOPIC
 FLOAT PASSIVELY IN WATER
CURRENTS
 MOST ARE PHOTOSYNTHETIC

10.  DIATOMS HAVE CELLWALL WITH
2 OVERLAPPING SHELLS
 WALLS ARE EMBEDDED WITH
SILICA SO THE WALLS ARE
INDESTRUCTABLE
 DIATOMS ARE THE CHIEF
PRODUCERS IN OCEANS

11.  DIATOMS HAVE LEFT BEHIND
LARGE AMOUNT OF CELLWALL
DEPOSITS IN THEIR HABITAT
 THIS ACCUMULATION OVER
BILLIONS OF YEARS THIS IS KNOWN
AS DIATOMACEOUS EARTH.

15.  MARINE
 PHOTOSYNTHETIC
 YELLOW,GREEN,BROWN,BLUE
OR RED DEPENDING ON THE MAIN
PIGMENTS
 MOST HAVE 2 FLAGELLA

16.  CELL WALL – STIFF CELLULOSE
PLATES ON OUTER SURFACE
 RED DINOFLAGELLATES –
UNDERGO RAPID MULTIPLICATION
– MAKE THE SEA APPEAR RED
(RED TIDES)
 RELEASE TOXINS – KILL OTHER
MARINE ANIMALS

20.  MAJORITY FRESH WATER
 PELLICLE PRESENT
 HELPS FOR BODY FLEXIBILITY
 2 FLAGELLA – SHORT AND LONG

21.  PRESENCE OFSUNLIGHT –
PHOTOSYNTHETHIC
 ABSENCE OF SUNLIGHT –
HETEROTROPHS
 PIGMENTSARE IDENTICAL TO THOSE
IN HIGHER PLANTS
 EUGLENA

24.  SAPROPHYTIC PROTIST
 BODY MOVES ALONG DECAYING TWIGS
AND LEAVES
 ENGULF ORGANIC MATERIALS
 FORM PLASMODIUM – AGGREGATION
(IN FAVOURABLE CONDITION)

25. UNFAVOURABLE CONDITION –
PLASMODIUM DIFFERENTIATES
FORMS FRUITING BODIES BEARING
SPORES AT THE TIP
SPORES – TRUE WALLS
EXTREMELY RESISTANT
DISPERSED BY AIR CURRENTS

28. HETEROTROPHS
LIVE AS PREDATORS OR PARASITES
PRIMITIVE RELATIVES OF ANIMALS

29. DIVIDED INTO 4 GROUPS
 AMOEBOID PROTOZOANS
 FLAGELLATED PROTOZOANS
 CILIATED PROTOZOANS
 SPOROZOANS

30. AMOEBOID PROTOZOAN
FRESH WATER,SEA WATER,MOIST SOIL
PSEUDOPODIA(FALSE FEET)
MOVE AND CAPTURE
MARINE FORMS HAVE SILICA SHELLS
AMOEBA,ENTAMOEBA

32. FLAGELLATED PROTOZOANS
FREELIVING / PARASITIC
FLAGEELA
PARASITIC FORMS – CAUSE DISEASE
LIKE SLEEPING SICKNESS
TRYPANSOMA

34. CILIATED PROTOZOANS
AQUATIC
1000’s OF CILIA
ACTIVELY MOVING
GULLET – CAVITY OPENS OUT
COORDINATED MOVEMENT OF CILIA
PARAMOECIUM

36. SPOROZOANS
INFECTIOUS SPORE LIKE
STAGE IN THEIR LIFE CYCLE
MALARIAL PARASITE
Plasmodium vivax
