Kingdoms of nature

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

  • animalia (animals),
  • plants (plants)
  • fungi (mushrooms),
  • protists (protozoarios),
  • bacteria (bacteria) and
  • 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 archaea (classified as bacteria) are actually more similar to eukaryotes despite being prokaryotes.

Kingdom Animalia (animals)

Dominio : Eukarya .

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

Cell organization : multicellular.

Nutrición : heterótrofos.

Reproduction : sexual.

Examples : humans, bees, worms, corals, fish.

Kingdom Plantae (plants)

Dominio : Eukarya .

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

Cell organization : multicellular.

Nutrition : autotrophs.

Reproduction : sexual and asexual.

Examples : pines, grasses, cereals, shrubs.

Kingdom Fungi (mushrooms)

Dominio : Eukarya .

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

Cell organization : unicellular / multicellular.

Nutrición : heterótrofos.

Reproduction : asexual and sexual.

Examples : yeast, mold, fungus.

Reino Protista (protozoarios)

Dominio : Eukarya .

Cell type : eukaryotic cell;

Cellular organization : mostly unicellular.

Nutrición : heterótrofos / autótrofos.

Reproduction : mainly asexual.

Examples : protozoa, amoebas.

Know the difference between:

Archaea Kingdom (archaea)


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

Cell organization : unicellular.

Nutrición : autótrofos / heterótrofos.

Reproduction : by binary fission.

Examples : methanogens, thermophiles.

Kingdom Bacteria (bacteria)


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

Cell organization : unicellular, colony formation.

Nutrición : autótrofos / heterótrofos.

Reproduction: by binary fission.

Examples : Enterobacteriaceae, Staphylococci, Streptococci.
