Classification of Living Organisms

The video tutorial explains Whitaker's five kingdom classification system, detailing the criteria used for classification, such as cell complexity, organism complexity, and mode of nutrition. It covers each kingdom: Monera, Protista, Plantae, Fungi, and Animalia, highlighting their unique characteristics and the rationale behind their classification.

What is the main reason for continuing to use Whitaker's five-kingdom classification?

• It is the most recent classification system.

• It is based on natural classification considering multiple parameters.

• It is the only system that includes all living organisms.

• It is the simplest classification system.

Which type of cells are considered the simplest according to the cell complexity criterion?

• Unicellular eukaryotes

• Prokaryotic cells

• Multicellular organisms

• Eukaryotic cells

In Whitaker's classification, which kingdom includes only prokaryotic organisms?

• Fungi

• Animalia

• Protista

• Monera

What distinguishes simple organisms from complex ones in the organism complexity criterion?

• Number of cells

• Presence of a cell wall

• Type of nutrition

• Presence of a nucleus

Which kingdom is characterized by having only unicellular eukaryotic organisms?

• Animalia

• Plantae

• Fungi

• Protista

What mode of nutrition is associated with organisms that depend on dead organic matter?

• Parasitic

• Saprotrophic

• Heterotrophic

• Autotrophic

Which kingdom includes organisms that are all autotrophs?

• Animalia

• Fungi

• Plantae

• Monera

In the five-kingdom classification, which kingdom lacks a cell wall?

• Fungi

• Protista

• Animalia

• Monera

What is the primary component of the cell wall in the kingdom Plantae?

• Chitin

• Peptidoglycan

• Cellulose

• Lignin

Which kingdom is characterized by organisms with a well-developed organ system?

• Animalia

• Monera

• Protista

• Fungi
