The 6 kingdoms of nature and their characteristics

Living things are currently classified into six different kingdoms of nature:

  • animal (animals),
  • plants (plants),
  • fungi (fungi),
  • protist (protozoa),
  • bacteria (bacteria) i
  • archaea (archaea).

In the past living organisms were classified into five kingdoms: animals, plants, fungi, protozoa and bacteria. With the implementation of molecular techniques it was discovered that archaebacteria (classified as bacteria) are actually more similar to eukaryotes despite being prokaryotic.

kingdom animal (animals)

Control: Eukarya.

Cell type: eukaryotic animal cell, absence of chloroplasts and cell wall.

Cellular organization: multicellular

nutrition: heterotrophs.

reproduction: sexual

examples: human beings, bees, worms, corals, fish.

kingdom Plantae (plants)

Control: Eukarya.

Cell type: eukaryotic plant cell; chloroplasts and cellulose cell wall present.

Cellular organization: multicellular

nutrition: autotrophs.

reproduction: sexual and asexual.

examples: pines, grasses, cereals, shrubs.

kingdom fungus (fungi)

Control: Eukarya.

Cell type: eukaryotic cell; absence of chloroplasts, presence of chitin cell wall.

Cellular organization: unicellular/ multicellular.

nutrition: heterotrophs.

reproduction: asexual and sexual.

examples: yeasts, mold, fungi.

kingdom protist (protozoa)

Control: Eukarya.

Cell type: eukaryotic cell;

Cellular organization: mostly unicellular.

nutrition: heterotrophs/autotrophs.

reproduction: mainly asexual.

examples: protozoa, amoebae.

Know the difference between:

kingdom Archaea (archaea)

Control: Archaea.

Cell type: prokaryotic cell (without a nucleus) and with a cell wall without peptidoglycan.

Cellular organization: unicellular.

nutrition: autotrophs/heterotrophs.

reproduction: by binary fission.

examples: methanogens, thermophiles.

kingdom bacteria (bacteria)

Control: bacteria.

Cell type: prokaryotic cell (without a nucleus) and with a peptidoglycan cell wall.

Cellular organization: unicellular, colony formation.

nutrition: autotrophs/heterotrophs.

Playback: by binary fission.

examples: enterobacteria, staphylococci, streptococci.
