Class 9 Science — Diversity and classification

Place an organism in one of the five kingdoms, run the hierarchy from kingdom down to species, and read and write a scientific name in the binomial system.

Name: ________________________

Before you start

The seven bands of the classification pyramid, each one named.

1234567
  1. 1. Kingdom, the broadest group of the seven
  2. 2. Phylum
  3. 3. Class
  4. 4. Order
  5. 5. Family
  6. 6. Genus
  7. 7. Species, the narrowest group of the seven

Each band sits inside the one above it, and the organisms in it share more features than the organisms in the band above. It works like an address, narrowing from country down to house.

  1. 1.Sort each organism into its kingdom.

    Groups: Monera · Protista · Fungi · Plantae

    • Spirogyra
    • Paramecium
    • Yeast
    • Cyanobacteria
    • Amoeba
    • Mushroom

  2. 2.A mango tree's scientific name has two words: Mangifera comes first. Which of the two words names the species? Write it.

  3. 3.Which of these is written according to the rules for a scientific name?

    • a) panthera Tigris, in italics
    • b) Panthera tigris, in italics
    • c) PANTHERA TIGRIS, in italics
    • d) Tigris panthera, in italics

  4. 4.Yeast is a single-celled organism, yet it is not placed in Protista. Why is it in Fungi?

    • a) It is multicellular under the microscope
    • b) It makes its own food by photosynthesis
    • c) It is a prokaryote
    • d) Its cell wall is made of chitin

  5. 5.In 1977 Carl Woese proposed a system with three groups above the kingdoms. What are they?

    • a) Bacteria, Archaea and Eukarya
    • b) Monera, Protista and Fungi
    • c) Chordata, Non-chordata and Protochordata
    • d) Plantae, Animalia and Fungi

  6. 6.A geologist digs down through undisturbed rock layers. What does the chapter say she will generally find as she goes deeper?

    • a) No fossils at any depth
    • b) Fossils of more complex organisms
    • c) Fossils of simpler organisms
    • d) The same organisms at each depth

  7. 7.Match each kingdom to what defines it.

    • Monera
    • Protista
    • Fungi
    • Plantae
    • Animalia
    • Multicellular eukaryotes with cellulose cell walls that make their own food
    • Eukaryotes with chitin cell walls that feed on dead matter
    • Single-celled eukaryotes
    • Prokaryotes, whose nucleus has no membrane around it
    • Multicellular eukaryotes without cell walls that feed on other organisms

  8. 8.Amoeba, Paramecium and Euglena are grouped together. What do they have in common that puts them in one kingdom?

    • a) They are multicellular and make their own food
    • b) They are prokaryotes with no true nucleus
    • c) They have cell walls made of chitin
    • d) They are single-celled eukaryotes living in water or moist places
