2. WHAT IS PROTIST?
• THEY ARE EUKARYOTES
• HAVE A NUCLEUS AND OTHER MEMBRANE-BOUND
ORGANELLES
• MOST HAVE MITOCHONDRIA
• THEY CAN BE PARASITES.
• THEY ALL PREFER AQUATIC OR MOIST
ENVIRONMENTS.
3.
4. HOW PROTIST OBTAIN ENERGY?
GROUP OF PROTIST
1. PHOTOTROPHS- PRODUCE THEIR OWN FOOD
2. HETEROTROPHS- FEED ON OTHER ORGANISM
3. SPOROZOAN- NON-MOTILE, THEY ARE
PARASITES
6. WHAT IS PHOTOTROPHS?
•PIGMENT TO CAPTURE LIGHT
(CHLOROPHYLL)
•A STRUCTURE TO HOLD THE PIGMENT
( CHLOROPLASTS)
• A STRUCTURE TO CAPTURE LIGHT ( FLAT
LEAVES)
10. CHARACTERISTICS OF GREEN
ALGAE
•DIFFER IN SIZE AND SHAPE
•SOME ARE UNICELLULAR
•OTHER FORMS COLONIES, SHEET, FILAMENT,
TUBES, AND RIBBONS
•GROW IN MARINE ENVIRONMENT
11. •THE MARINE GREEN ALGA CAULERPA
LENTILLIFERA IS EATEN FRESH AS
SALAD
12. GOLDEN ALGAE
• IS MASKED BY YELLOW PIGMENT AND BROWN
MASK PIGMENT.
• MEMBERS OF THIS GROUP ARE MOSTLY
MICROSCOPIC.
• THEY STORE FOOD FROM LEUCOSIS OIL OR
CHRYSOLAMINARIN.
• BROWN ALGAE ARE THE LARGEST OF THE ALGAE
SPECIES (CAN GROW TO MORE THAN 30 METERS
LENGTH)
14. WHAT IS THE IMPORTANCE OF BLADDER IN
BROWN ALGAE?
“THE BLADDERS ENABLE THEM TO FLOAT UP
TOWARD THE WATER SURFACE, MAXIMIZING
SUNLIGHT ABSORPTION FOR
PHOTOSYNTHESIS”
15. DO YOU KNOW THAT BROWN
ALGAE HAVE SOMETHING TO DO
WITH YOUR FAVORITE ICE CREAM
OR TOOTHPASTE? SOME MEMBERS
OF THE GROUP CONTAIN ALGINIC
ACID USED AS AN INGREDIENT IN
MAKING THESE,
16. RED ALGAE
• STORING FOOD IN THE FORM OF FLORIDEAN
STARCH.
• RED PIGMENT MASK
• CAN CHANGE COLOR DEPENDING ON WEATHER
THEY ARE EXPOSE
• HELP TO FORM CORAL REEF BECAUSE OF THEIR
ABILITY TO PRODUCE CALCIUM CARBONATE
17. ONE OF THE EXAMPLE MICROORGANISM IN
RED ALGAE IS EUCHEUMA HAVE HAVE ABILITY
TO PRODUCE AGAR AND IT IS ONE OF THE
INGREDIENT IN MAKING OF GULAMAN .
18. WHY LIGHT IS IMPORTANT TO
ALGAE?
“ALGAE ARE AUTOTROPHIC, MEANING THEY
REQUIRE SUNLIGHT TO GROW AND SURVIVE.
ALGAE GET THEIR ENERGY DIRECTLY FROM
LIGHT AND ALSO GO THROUGH THE
PROCESS OF PHOTOSYNTHESIS”
21. PYRODINIUM BAHAMENSE VAR. COMPRESSUM
THEY ARE THE ONES THAT CAN CAUSE RED TIDE WHEN
PRESENT IN LARGE NUMBERS
THIS MICROORGANISM IS
CONTAIN TOXIC.
AND CAN CAUSE PARALYSIS
22. EUGLENOIDS
•ARE MICROSCOPIC AND UNICELLULAR
•EUGLENA BELONGS TO THIS GROUP
•IT LIVES IN FRESHWATER BODIES
•THIS GROUP HAVE A WHIPLIKE FLAGELLUM
FOR MOVEMENT
•SOME EUGLENOIDS HAVE CHLOROPHYL
24. EUGLENA CHARACTERISTIC
•WHEN LIGHT IS AVAILABLE TO, IT
MAKES FOOD UTILIZING CHLOROPHYLL
•IN THE ABSENCE OF LIGHT IT ABSORBED
NUTRIENT FROM DEAD ORGANIC
MATTER
25. HETEROTROPHS
• NO PERMANENT STRUCTURE FOR
MOVEMENT FOR MOVEMENT
• THEY MOVE BY MEANS OF PSEUDOPODS OR
PSEUDOPODIA
• THE EXTENSION AT THE SIDES OF THESE
MICROORGANISM ENABLE THE
HETEROTROPHS TO MOVE
27. ENTAMOEBA HISTOLYTICA
IS A HARMFUL SPECIES OF AMOEBA
LIVING IN FRESHWATER BODIES. ONCE
THIS MICROORGANISM ENTER TO OUR
BODY THE GASTROINTESTINAL TRACT IS
INFECTED CAUSING AMOEBIASIS
31. SLIME AND WATER MOLDS
•SLIME MOLDS ARE USUALLY THE COLORED
YELLOW, ORANGE, OR WHITISH
THEY MAY SEE ON DAMP AND
ROTTING LOGS
THEY FEED ON BACTERIA AND
DECAYING PLANT MATERIALS
37. FUNGI• HUMID OR MOIST PLACE
• EUKARYOTIC FUNGI
• NO CHOLOROHYL
• CANNOT PRODUCE THEIR OWN FOOD
• THEY SURVIVE BY LIVING ON A HOST ORGANISM
• OTHERS FEED ON DECAYING MATTERS AND ARE CALLED
SAPROPHYTES
• CELL WALL BUT ARE MADE UP OF CHITIN
• INVOLVING IN DECOMPOSING
41. FUNGI CAN BE CLASSIFIED ACCORDING TO
THE KIND OF FRUITING STRUCTURE
42. VOLVARIELLA AND PLEUROTUS SAJOR-
CAIJU (OYSTER MUSHROOM) ARE USE TO
UTILIZE IN US SOY SAUCE MAKING
INCLUDE THE YEAST
43. FUNGAL SPECIES CAN BE HARMFUL
•ASPERIGILLUS FLAVUS PRODUCE AFLATOXIN
A POISONOUS SUBSTANCE.
•TRICHOPHYTON MENTAGROPHYTES AND T.
RUBRUM- CAUSE ATHLETE’S FOOT
•T. RUBRUM CAN ALSO CAUSE RINGWORM
