Kingdom Protista

Question 1

Protista are different from minerals because they have:

Answer 1

• a membrane Boyd nucleus
• organelles
• sexual reproductive cycle

Question 2

There are three types of protists;

Answer 2

A. Zooplankton: animal like protists
B. Phytoplankton: plant like protists
C. Slime Molds: fungus like protists

Question 3

Common characteristics

Answer 3

Most are motile (can move)
Unicellular(more) or Multicellular
Eukaryotic ( have membranes and bound nucleus)

Question 4

A. Zooplankton / protozoans

Answer 4

• heterotrophic
• grouped by type of locomotion
• four phyla
  1. Phylum ciliophora
  2. Phylum rhizopoda
  3. Phylum zoomastigophora
  4. Phylum sporozoa

Question 5

1. Phylum ciliophora

Answer 5

Example: paramecium

• have cilia to help them move
• have a groove to collect food
  “Groove” do not do photosynthesis

Question 6

2. Phylum rhizopoda

Answer 6

Example: amoeba

• moves by pseudopods ( false feet)
• salt and fresh water

Question 7

3. Phylum sporozoa

Answer 7

• non-motile protists
• cause serious disease in humans
• example: plasmodium ( causes malaria)
• do not move on their own

Question 8

4. Phylum zoomastigophora

Answer 8

• have flagella for movement
• most are parasites ( host - live in)
• reproduce asexually ( binary fission)
• trypanosoma brucci, responsible for African sleeping sickness

Question 9

B. Phytoplankton

Answer 9

• plants like protists
• contain chlorophyll
• unicellular ( some multicellular)
• made up of 5 Phyla
  1. Euglenophta ( euglena)
  2. Pyrrophyta ( dinoflagellates)
  3. Chlorophyta (algae)
  4. Rhodophyta (red algae)
  5. Chrysophyta (diatoms)

Question 10

1. Euglenophyta

Answer 10

Example: euglena

Question 11

2. Pyrrophyta

Answer 11

(Dinoflagella)

• flagellates - spinning motion
• unicellular, photosynthetic

Question 12

3. Chlorophyta

Answer 12

(Algae)

• cell wall with cellulose
• contain chlorophyll

Example: Spirogyra

Question 13

4. Rhodophyta

Answer 13

Red algae

• ribbon - like appearance
• may be multicellular

Question 14

5. Chrysophyta

Answer 14

• diatoms
• hard shells
• food for small aquatic animals, produce oxygen (75% oxygen on earth)

Question 15

C. Slime Molds

Answer 15

• fungus- like protists
• consumers, found on forest food
• heterotrophic by ingestion
• usually exists as mass of cells surrounded by slime coating
• slide along ground, ingesting materials
