  • CThey are all multicellular.

Q2:

Which of the following lists states the classes of the Protozoa phylum?

  • AFlagellata, Zygomycota, Ascomycota, and Basidiomycota
  • BSarcodina, Ciliophora, Flagellata, and Sporozoa
  • CCiliophora, Rhodophyta, Chlorophyta, and Tracheophyta
  • DSporozoa, Archaebacteria, and Eubacteria

Q3:

Organisms belonging to the kingdom Protista are eukaryotic. Which of the following best explains what this means?

  • AThe cells of the organism contain the majority of their genetic material in multiple plasmids.
  • BThe cells of the organism contain the majority of their genetic material in a single-looped chromosome.
  • CThe cells of the organism contain the majority of their genetic material in a membrane-bound nucleus.
  • DThe cells of the organism do not contain any genetic material.

Q4:

Which of the following statements about the nutrition of the organisms of the kingdom Protista is correct?

  • AOrganisms belonging to this kingdom are exclusively heterotrophic.
  • BOrganisms belonging to this kingdom are exclusively autotrophic.
  • COrganisms belonging to this kingdom can be autotrophic or heterotrophic.

Q5:

The kingdom Protista is divided into multiple phyla.

Which of the following statements best describes organisms belonging to the Chrysophyta phylum?

  • AOrganisms are unicellular, they inhabit fresh water or salt water, and most contain chloroplasts to carry out photosynthesis.
  • BOrganisms move by the use of flagella, their cells contain photosynthetic pigments, and nearly all species are classed as phytoplankton.
  • COrganisms are mostly unicellular algae, with their cells often containing chloroplasts and the cell walls containing silica.
  • DOrganisms are unicellular, they often inhabit water or moist soils, and they can act as parasites.

Q6:

The picture provided shows Amoeba proteus, an organism belonging to the kingdom Protista.

Which of the following statements describes the characteristics of organisms belonging to the kingdom Protista?

Amoeba proteus
  • AOrganisms are eukaryotic, they contain membrane-bound organelles like a nucleus, and the majority are unicellular.
  • BOrganisms are prokaryotic, autotrophic, and multicellular.
  • COrganisms are prokaryotic, so they do not contain a membrane-bound nucleus, and they are all unicellular.
  • DOrganisms are eukaryotic, they all contain photosynthetic pigments, and the majority are multicellular.

Q7:

The kingdom Protista is divided into multiple phyla.

Which of the following statements best describes organisms belonging to the Pyrrophyta phylum?

  • AOrganisms are mostly unicellular algae, with their cells often containing chloroplasts and the cell walls containing silica.
  • BOrganisms move by the use of flagella, their cells contain photosynthetic pigments, and nearly all species are classed as phytoplankton.
  • COrganisms are unicellular, they often inhabit water or moist soils, and they can act as parasites.
  • DOrganisms are unicellular, they inhabit fresh water or salt water, and most contain chloroplasts to carry out photosynthesis.

Q8:

The following is a list of the different classes of Protozoa:

  1. Sarcodina
  2. Ciliophora
  3. Flagellata
  4. Sporozoa

A single-celled eukaryotic organism is found that possesses a foot-like extension to aid its movement. Which of the classes listed is this organism most likely to belong to?

  • ASporozoa
  • BSarcodina
  • CCiliophora
  • DFlagellata

Q9:

Kingdom Protista is divided into multiple phyla. Which of the following is not a phylum of kingdom Protista?

  • AChrysophyta
  • BProtozoa
  • CBryophyta
  • DEuglenophyta
  • EPyrrophyta

Q10:

The picture provided shows an organism belonging to the Protozoa phylum of kingdom Protista. Which of the following statements best describes the characteristics of organisms belonging to this phylum?

Organism
  • AOrganisms are unicellular, live in areas with high plant density, and are autotrophic.
  • BOrganisms can be multicellular or unicellular and are all parasitic, so they live on the bodies of other organisms.
  • COrganisms are mostly unicellular, commonly live in moist soil or water, and are heterotrophic.
  • DOrganisms are multicellular, live only on land, and are heterotrophic.
