Who proposed the Five Kingdom Classification system?

Aristotle
Linnaeus
R.H. Whittaker
Haeckel
3

R.H. Whittaker proposed the Five Kingdom Classification in 1969, which included Monera, Protista, Fungi, Plantae, and Animalia.

Which of the following statements about bacterial reproduction is correct?

Bacteria reproduce primarily by binary fission.
Bacteria undergo mitosis during cell division.
Bacteria reproduce only sexually.
Bacteria have a multicellular body structure.
1

Bacteria primarily reproduce asexually by binary fission, a rapid method of cell division.

Which of the following is a characteristic of Kingdom Monera?

Eukaryotic cell structure
Presence of nuclear membrane
Unicellular prokaryotic organisms
Multicellular body organization
3

Kingdom Monera includes unicellular prokaryotic organisms, such as bacteria, that lack a nuclear membrane.

Which of the following kingdoms includes organisms that lack a nuclear membrane?

Monera
Protista
Fungi
Plantae
1

Kingdom Monera consists of prokaryotic organisms that lack a well-defined nuclear membrane.

Which of the following statements about Kingdom Monera is correct?

Monerans include both bacteria and cyanobacteria.
Monerans possess a well-defined nucleus.
Monerans have membrane-bound organelles.
Monerans reproduce only sexually.
1

Kingdom Monera includes bacteria and cyanobacteria, which are prokaryotic organisms.

Which of the following is NOT a characteristic of Kingdom Fungi?

Heterotrophic mode of nutrition
Presence of chitin in the cell wall
Multicellular body organization only
Reproduction by spores
3

Fungi can be unicellular (e.g., yeast) or multicellular (e.g., mushrooms). Therefore, stating that they are only multicellular is incorrect.

Which of the following statements about Kingdom Monera is incorrect?

Monerans are prokaryotic organisms.
Monerans reproduce mainly by binary fission.
All Monerans are autotrophic.
Some Monerans can fix atmospheric nitrogen.
3

Monerans include both autotrophic and heterotrophic organisms, not just autotrophic ones.

Which of the following kingdoms includes organisms that are exclusively heterotrophic?

Monera
Protista
Fungi
Plantae
3

Kingdom Fungi includes organisms that are exclusively heterotrophic, obtaining nutrition through saprophytism or parasitism.

Which of the following statements about bacteria is correct?

All bacteria are pathogenic to humans.
Bacteria lack membrane-bound organelles.
Bacteria have a well-defined nucleus.
Bacteria reproduce only by sexual reproduction.
2

Bacteria lack membrane-bound organelles such as the nucleus, mitochondria, and endoplasmic reticulum.

Who was the first to attempt a scientific basis for the classification of organisms?

Linnaeus
Aristotle
Whittaker
Haeckel
2

Aristotle was the first to attempt a scientific classification of organisms based on simple morphological characteristics.
