Protists (DOLT)

Question 1

multicellular or unicellular?

Answer 1

mostly unicellular

Question 2

aquatic or terrestrial?

Answer 2

mainly aquatic- means water contact is necessary for suvival

Question 3

reproduction

Answer 3

binary fission

Question 4

sexual reproduction

Answer 4

very adapted protists

Question 5

energy

Answer 5

autotrophic and heterotrophic

Question 6

autotrophs

Answer 6

photosynthesis and chemosynthesis

Question 7

heterotrophs

Answer 7

ingest smaller organisms or their waste
secrete digestive enzymes and absorb digested food
able to move around by themselves

Question 8

locomotion

Answer 8

flagella (longer than cilia and range from 1-2 per cell)
cilia (shorter than flagella and range from 10-100s per cell)
pseudopods “fake feet”

Question 9

classification based on other kingdoms

Answer 9

1. animal-like: heterotrophic and motile
2. plant-like: photosynthetic
3. fungi-like: absorbtive heterotrophic

Question 10

chemosynthesis

Answer 10

sulfur based chemicals and heat used to produce larger molecules that store energy

Question 11

amoeba

Answer 11

“blob-like”
flexible membranes
pseudopods- used for movement and catching food

Question 12

paramecium

Answer 12

“slipper-like”
oral grove
cilia- draw food into oral grove
faster than amoeba

Question 13

euglena

Answer 13

autotrophs
green colour- contain chloroplasts
flagellum

Question 14

volvox

Answer 14

autotrophs
spherical colony of euglena-like protists
flagella
move in a rolling way

Question 15

amoeba dysentry

Answer 15

water borne digestive illness

coined the phrase “don’t drink the water” for travellers

Question 16

diatoms

Answer 16

outer covering made of silica

photosynthetic plankton

Question 17

silica

Answer 17

ground into diatomaceous earth using fine filter

biodegradable insecticides
