Protists

Question 1

are the most diverse of all eukaryotes.

Answer 1

Protists

Question 2

one celled “first” “animals”

Answer 2

Protozoa

Question 3

primitive “first” “plants”

Answer 3

Protophyta

Question 4

all one-celled eukaryotic organisms
were classified as

Answer 4

Protists

Question 5

that are not plants, animals, or fungi”.

Answer 5

all eukaryotic
cells

Question 6

Protozoa = one celled “first” “animals” and
• Protophyta = primitive “first” “plants”
• Then, all one-celled eukaryotic organisms
were classified as protists.
• Now, the group is considered “all eukaryotic
cells that are not plants, animals, or fungi”.

Answer 6

Once upon a time

Question 15

Is the most diverse

Answer 15

The protist kingdom

Question 16

Some protists are

Answer 16

Unicellular while others are multicellular

Question 17

The wide variety of protists have so many characteristics that made difficult to classify, but scientists develop a method to classify into 3 separate categories

Answer 17

Animal-like, plant-like (algae), fungus

Question 18

Animal-like and feed on bacteria and smaller protists

Answer 18

Amoeba

Question 19

Animal-like protists that live in fresh water feed on bacteria and smaller protists

Answer 19

Paramecium- paramecia

Question 20

Are unicellular algae that lives in fresh water and can make its own food in presence of sunlight

Answer 20

Euglenoids Euglena

Question 21

Are heterotrophs and use spores to reproduce

Answer 21

Fungus-like protists like fungi (slime mold)

Question 22

may be autotrophic,
heterotrophic, or mixotrophic
organisms:

Answer 22

Protists

Question 23

Photosynthetic: plant-like

Answer 23

Autotrophic

Question 24

Ingestive: animal-like

Answer 24

Heterothropic

Question 25

Absorptive: fungus-like

Answer 25

Heterotrophic

Question 26

combine | photosynthesis and food ingestion.

Answer 26

Mixotrophic organisms

Question 27

move with | cilia….They belong to a group known as the Ciliates or Ciliaphora

Answer 27

Some Protozoa

Question 28

help protists to swim and capture food

Answer 28

Cilia

Question 29

Many protists have

Answer 29

a | contractile vacuole…..a pump that will contract and pump excess water out of the cell.

Question 30

use pseudopodia for movement & feeding.

Answer 30

Some protists

Question 31

are “false” “feet” or cellular extensions that may bulge from almost anywhere on the cell. Typically occurs in heterotrophs, such as the Sarcodines, like Amoebas.

Answer 31

Pseudopodia

Question 32

Amoeba extends pseudopodia around food particle until they join, enclosing the particle in a membrane-bound vesicle. A lysosome merges with the new food vacuole, dumping its enzymes in to digest the food. The products of digestion are then absorbed through the membrane.

Answer 32

Phagocytosis

Question 33

Algae are plantlike protists. | Plantlike protists can be single-celled or multicellular.

Answer 33

Plantlike protists

Question 34

are a large group of plantlike protists.

Answer 34

Euglenoids

Question 35

have one or two flagella.

Answer 35

Mostly photosynthetic

are a large group of plantlike protists. Mostly photosynthetic, have one or two flagella.

Answer 36

Euglenoids

Question 38

.............moves toward the light, has a ............. which is light sensitive, movement known as a .................

Answer 38

Euglena.........red eyespot.......positive phototropism.
