5 KINGDOM CLASSIFICATION

Q1. Consider the characteristics of organisms within the Kingdom Monera and Kingdom Protista. Which of the following statements accurately differentiates the two kingdoms based on cellular structure?

[ANALYSIS]

• A. Kingdom Monera consists of multicellular organisms, while Kingdom Protista contains unicellular organisms.

• B. Organisms in Kingdom Monera lack a nucleus, whereas Kingdom Protista organisms have a well-defined nucleus.

• C. Both Monera and Protista contain organisms with membrane-bound organelles.

• D. Both Monera and Protista include organisms with cellulose-based cell walls.

If an organism is observed to have chitin in its cell wall and lacks chlorophyll, which kingdom is it most likely to belong to?

[ANALYSIS]

• A. PLANTAE

• B. PROTISTA

• C. MONERA

• D. FUNGI

Which of the following scenarios illustrates the characteristic of motility as found in Kingdom Protista?

[ANALYSIS]

• A. A bacterium moving using flagella in response to environmental changes.

• B. A Paramecium swimming in water using its cilia for movement.

• C. A multicellular fungus growing towards a food source.

• D. A plant leaf adjusting to face the sunlight.

Kingdom Plantae and Kingdom Animalia are both multicellular, yet they have fundamental differences in cell structure and function. Which of the following best highlights one of these key differences?

[ANALYSIS]

• A. Cells in Plantae are devoid of a nucleus, unlike those in Animalia.

• B. Animalia possess a rigid cell wall, which is absent in Plantae.

• C. Plantae cells have chloroplasts for photosynthesis, while Animalia cells lack this organelle.

• D. Both Plantae and Animalia are heterotrophic.

A biologist discovers a unicellular organism in a sample of pond water. This organism has a well-defined nucleus, chloroplasts, and moves using a flagellum. To which kingdom does this organism most likely belong?

[APPLICATION]

• A. MONERA

• B. PROTISTA

• C. PLANTAE

• 4. D. ANIMALIA

While studying marine life, a scientist comes across a multicellular organism with no cell wall and no chlorophyll, yet it can move freely. Which of the following kingdoms does this organism most likely belong to?

[APPLICATION]

• A. Plantae

• B. Protista

• C. Animalia

• D. Fungi

Which of the following statements best describes Kingdom Fungi?

[UNDERSTANDING]

• A. They are all autotrophic and use sunlight to make their food.

• B. They are mainly multicellular, with a few exceptions, and have chitin in their cell walls.

• C. They possess chloroplasts and are similar to plants.

• D. They are unicellular organisms with prokaryotic cells.

Organisms in the Kingdom Animalia differ from those in Kingdom Plantae mainly because

[UNDERSTANDING]

• A. Animalia have a cell wall made of cellulose, while Plantae lack cell walls.

• B. Plantae have chloroplasts, while Animalia lack chloroplasts and are heterotrophic.

• C. Animalia reproduce by spores, whereas Plantae reproduce asexually only.

• D. Plantae are multicellular, while Animalia are unicellular.

Who proposed the five-kingdom classification system?

[RECALL]

• A. Carolus Linnaeus

• B. Robert Whittaker

• C. Ernst Haeckel

• D. Charles Darwin

The cell walls of fungi are primarily composed of:

[RECALL]

• A. Cellulose

• B. Chitin

• C. Lignin

• D. Peptidoglycan
