What is the lowest category in the hierarchical classification?

• Species

• Genus

• Family

• Order

The five kingdom system proposed by Whittaker in 1969 is based on three classification EXCEPT:

• Level of cell organisation

• Types of organism

• Habitat of organism

• Modes of nutrition

Which statement describe holozoic nutrition?

• The organism that convert organic into inorganic material

• The organism taking in food and have to be further broken down

• The organism makes its own food

The three domain system are of the following EXCEPT:

• Domain Monera

• Domain Bacteria

• Domain Archaea

• Domain Eukarya

Which domain is closely related to eukaryotes?

• Domain Bacteria

• Domain Archaea

What is the composition of cell wall in Domain Bacteria?

• Cell wall is lack peptidoglycan

• Cell wall made up of peptidoglycan

• Cell wall made up of cellulose (plant) and chitin (fungi)

Diversity of bacteria based on .....

• Cell wall and cell shape

• Cell shape and RNA polymerase

• Cell shape and Gram-stain

• Gram-stain and RNA polymerase

In Gram staining technique, Gram-Negative bacteria will produce

• purple colour

• red colour

• white colour

• orange colour

Why Gram-Negative is more pathogenic?

• Due to its negative charge on cell wall

• Due to thin cell wall

• Due to its staining which makes them become virulent

• Due to outer membrane that consist of lipopolysachharide which is toxic

The two major phyla of Algae is classified based on...

• its locomotion

• its habitat

• its mode of nutrition

• its photosynthetic pigments
