Question 1

what are the modes of nutrition for protist

Answer 1

• phototrophic
• heterotrophic
• mixotrophic

Question 2

primary production

Answer 2

amount of energy stored by photoautotrophs

Question 3

what are phototrophic organisms called

Answer 3

algae

Question 4

what are heterotrophic organisms called

Answer 4

protozoa

Question 5

phagocytosis

Answer 5

uptake of large particles or entire organisms by pinching inward of plasma membrane

Question 6

mixotrophic

Answer 6

organism is capable of ingestion and photosynthesis

Question 7

what are the three common modes of transportation

Answer 7

1. cilia
2. flagella
3. pseudopodia

Question 8

cilia

Answer 8

• microscopic hair like projections
• extend from surface of cell
• rhythmical motion
• act in unison to bring motion

Question 9

flagella

Answer 9

• long, thread like appendages
• found in pairs or singly

Question 10

pseudopodia

Answer 10

• temporary projections of the cytoplasm
• used to move or engulf food

Question 11

taxonomic group of euglena

Answer 11

Euglenozoa

Question 12

taxonomic group of paramecium

Answer 12

ciliates

Question 13

what are the two taxonomic groups that can have various organism

Answer 13

dinoflagellates and diatoms

Question 14

taxonomic group of Amoeba

Answer 14

Amoebozoa

Question 15

taxonomic group of Oscillatoria

Answer 15

blue-green algae

Question 16

taxonomic group of spirogyra

Answer 16

green algae

Question 17

what is euglenas mode of locomotion

Answer 17

flagella

Question 18

are euglena more tolerant to an increase of decrease in salinity

Answer 18

increase

Question 19

do euglena have anterior and posterior ends?

Answer 19

yes

Question 20

what is the mode of nutrition for euglena

Answer 20

mixotrophs

Question 21

what is the distinctive color of euglena

Answer 21

green

Question 22

what is one way to slow down ciliates so they can be observed

Answer 22

prepare a wet mount of the ciliates with yeast that has been stained
- slow down to feed on yeast
- use congo red stain

Question 23

congo red

Answer 23

• pH indicator
• paramecium’s food vacuoles change color as pH changes during digestion of yeast
• red= above 5.2
• blue/purple= below 3

Question 24

do paramecium have anterior and posterior ends

Answer 24

yes

Question 25

do the paramecium move fast or slow

Answer 25

move fast with cilia

Question 26

mode of nutrition for paramecium

Answer 26

heterotrophic

Question 27

what is the distinctive shape of paramecium

Answer 27

oval with pointed/sharp end

Question 28

what is when dinoflagellates "bloom"

Answer 28

reproduce very rapidly and cause water to appear red - red tides (harmful to other organisms)

Question 29

what type of cell wall do dinoflagellates have

Answer 29

cellulose

Question 30

what makes up the cell wall in the dinoflagellates

Answer 30

cellulose plates and perpendicular grooves

Question 31

what is the structure of diatoms

Answer 31

enclosed by cell wall made of silica - cell wall have two valves

Question 32

what are the possible shapes of diatoms

Answer 32

elongated boat shaped bilaterally symmetrical radially symmetrical

Question 33

why are diatoms important

Answer 33

produce carbohydrates and oxygen

Question 34

what is the body of the amoeba

Answer 34

unicellular no fixed body shape no hard outer covering

Question 35

how do amoeba move

Answer 35

fast and smooth

Question 36

how do amoeba capture food

Answer 36

pseudopodia

Question 37

what are the main components of blue-green algae

Answer 37

unicellular filamentous primarily freshwater

Question 38

how do Oscillatoria move

Answer 38

slow oscillating motions the filaments generate

Question 39

how do Oscillatoria reproduce

Answer 39

fragmentation - able to break off and then re-grow

Question 40

what are the basis of structure of green algae

Answer 40

unicellular colonial filamentous multicellular primarily freshwater

Question 41

what do green algae group have that often associate them with being related to plants

Answer 41

presence of chlorophyll a and b cellulosic cell wall
