The five-kingdom classification system was proposed by Robert Whittaker.

Taxonomy is the scientific study of classification of organisms.

Viruses are considered non-living entities as they cannot carry out metabolic processes independently.

The primary mode of nutrition in the kingdom Animalia is heterotrophic.

Archaebacteria are known for their ability to thrive in extreme environments.

The kingdom Monera includes unicellular and prokaryotic organisms.

The kingdom Plantae is characterized by multicellular and autotrophic organisms.

The kingdom Plantae is characterized by autotrophic organisms that perform photosynthesis.

Eukarya is characterized by the presence of a true nucleus in its cells.

Algae are classified under the kingdom Protista.

Fungi have chitin in their cell walls, distinguishing them from plants.

The kingdom Animalia consists of multicellular and heterotrophic organisms.

Plants are characterized by having cellulose in their cell walls.

The kingdom Animalia is defined by multicellular and heterotrophic organisms.

Prokaryotic cells have circular DNA and lack a true nucleus.

Plants have cell walls made of cellulose and are primarily autotrophic.

Viruses can only reproduce inside host cells, as they lack cellular structure and metabolism.

Organisms can be classified using morphological, physiological, and genetic methods.

Paramecium is a unicellular eukaryote.

Euglena is a unicellular organism.

Fungi is not a domain; it is a kingdom within the domain Eukarya.

Viruses are not classified as a domain of life.

Viruses are not included in the five-kingdom classification as they are not considered living organisms.
