THEY HAVE A CELLULOSE CELLS WALLS WHICH CONTAIN CHLOROPHYLL A AND B: AND THEY STORES STARCH THEY ARE MOST MICROSCOPIC ELTHOUGH THEY MAY BE EITHER UNICELLULAR OR MULTICELLULAR

A

GREEN ALGAE

25
Q

IT IS A UNICELLULAR OR FILAMENTOUS ALGAE WITH COMPLEX CELL WALLS THAT CONSIST OF PECTIN AND A LAYER OF SILICA: TWO PARTS OF THE WALL FIT TOGETHER LIKE THE HALVES OF PETRI DISH, THEY STORE ENERGY CAPTURED THROUGH PHOTOSYNTHESIS IN THE FORM OF OIL.

A

DIATOM

26
Q

WHAT ACID THAT DIATOM PRODUCES?

A

DOMOIC ACIDIT

27
Q

IT IS A NEUROTOXIN THAT CAUSES AMNESIC SHELLFISH POISONING

A

DOMOIC ACID

28
Q

IT IS A SYMPTOMS INCLUDE DIARRHEA AND MEMORY LOSS

A

AMNESIC SHELLFISH POISONING

29
Q

IT IS A UNICELLULAR ALGAE COLLECTIVELY CALLED PLANKTON

A

DINOFLAGELLATES

30
Q

IT PRODUCE BREVETOXINS THAT CAUSES MASSIVE FISH KILLS, NEUROTOXIC SHELLFISH POISONING, AND RESPIRATORY DISTRESS, PARTICULARLY IN PEOPLE WITH ASTHMA

A

KARENIA BREVIS

31
Q

WHAT GENUS IS IN A LARGE CONCENTRATIONS GIVES THE OCEAN A DEEP RED COLOR(RED TIDE) PRODUCES SAXITOXINS THAT CAUSE PARALYTIC SHELLFISH POISONINGS (PSP):

A

ALEXANDRIUM

32
Q

IT PRODUCES CIGUATOXIN THAT CAUSES CIGUATERA

A

GAMBIERDISCUS TOXICUS

33
Q

WHAT IS THE BY PRODUCT OF PHOTOSYNTHESIS

A

O2

34
Q

IT IS A periodic increases in numbers of planktonic algae AND Blooms of dinoflagellates
are responsible for seasonal red ঞdes. Blooms of a certain few species indicate that the water in
which they grow is polluted because these algae thrive in high concentraঞons of organic materials that exist in sewage or industrial wastes.

DIATOM

36
Q

WHAT IS THE KINGDOM OF PROTOZOA

A

PROTISTA

37
Q

WHAT IS THE NUTRITIONAL TYPE OF PROTOZOA

A

CHEMOHETEROTROPH

38
Q

WHAT IS THE CELLULAR ARRANGEMENT OF PROTOZOA

A

UNICELLULAR

39
Q

WHAT IS THE FOOD ACQUISITION METHOD IN PROTOZOA

A

ABSOPTIVE: INGESTIVE(CYTOSTOME)

40
Q

WHAT IS THE CHARACTERISTIC FEATURES IN PROTOZOA

A

MOTILITY: SOME FORM CYTS

41
Q

IT IS A COMPLETE ORGANISM IN WHICH ALL LIFE ACTIVITIES OCCUR WITHIN THE LIMIST OF A SINGLE CELL MEMBRANE

A

PROTOZOAN

42
Q

IT IS MEANS AS FIRST ANIMALS MEANT TO DESCRIBE ANIMAL-LIKE NUTRITION.

A

PROTOZOA

43
Q

WHAT LOCOMOTION THAT PROTOZOA HAVE

A

PSEUDOPODIA, FLAGELLA AND CILIA

44
Q

IT IS IN WHICH THE ORGANELLES ARE DUPLICATED AND THE PROTOZOAN THEN DIVIDES INTO TWO COMPLETE ORGANISMS

A

FISSION

45
Q

ASEXUAL REPRODUCTION BEGINNING AS A PROTUBERANCE FROM THE PARENT CELL THAT GROWS TO BECOME A DAUGHTER CELL

A

BUDDING

46
Q

IT IS A MULTIPLE FISSION: THE NUCLEUS UNDERGOES MULTIPLE DIVISIONS BEFORE THE CELL DIVIDES. AFTER MANY NUCLEI ARE FORMED, A SMALL PORTION OF CYTOPLASM CONCENTRATES AROUND EACH NUCLEUS, AND THEN THE SINGLE CELL SEPARATES INTO DAUGHTER CELLS

A

SCHIZOGOMY

47
Q

two cells fuse, and a haploid nucleus (the micronucleus) from each cell migrates to the other cell. This haploid micronucleus fuses with the haploid micronucleus within the cell. The parent cells separate, each now a fertilized cell. When the cells later divide, they produce daughter cells with recombined DNA.

A

CONJUGATION

48
Q

Some protozoa produce gametes (gametocytes), which are haploid sex cells. During reproduction, two gametes fuse to form a diploid zygote.

A

SYNGAMY

49
Q

Under certain adverse conditions, some protozoa produce a protective capsule

A

CYST

50
Q

The cyst formed by members of the phylum Apicomplexa is

A

AN OOCYST

51
Q

WHAT DO YOU CALL TO THE PROTECTUVE COVERING OF THE PROTOZOA’S

A

PELLICLE

52
Q

Ciliates take in food by waving their cilia toward a mouthlike opening called

A

CYSTOSOME

53
Q

In all protozoa, digestion takes place in membrane-enclosed vacuoles, and waste may be eliminated through the plasma membrane or through a specialized

A

ANAL PORE

54
Q

Single-celled eukaryotes with a feeding groove in the cytoskeleton ad are spindle-shape and possess
flagella includes two phyla that lack mitochondria (Diplomonads and Parabasalids)

A

EUGLENOZOA

55
Q

move by extending blunt, lobe like projections of the cytoplasm called pseudopods. Any number of pseudopods can flow from one side of the ameba, and the rest of the cell will flow toward the pseudopods.

A

AMEBAE

56
Q

are not motile in their mature forms and are obligate intracellular parasites. THEY ARE characterized by the presence of a complex of special organelles at the apexes (tips) of their cells (hence the name).

A

APICOMPLEXA

57
Q

have cilia that are arranged in precise rows on the cell. They are moved in unison to propel the cell
through its environment and to bring food particles to the mouth.

A

CILIATES
