kingdoms of nature

Currently these beings are classified into six different kingdoms of nature and we present them below:

  • Animals (animals).
  • plantae (plants).
  • Fungus (fungi).
  • Protista (protozoa).
  • Bacteria (bacteria).
  • Archaea (Archaea).

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

Kingdom Animalia (animals)

Domain:  Eukarya .

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

Cellular organization: multicellular.

Nutrition: heterotrophs.

Reproduction: sexual.

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

Kingdom Plantae (plants)

Domain: 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 and bushes.

Kingdom Fungi (fungi)

Domain: Eukarya.

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

Cellular organization: unicellular – multicellular.

Nutrition: heterotrophs.

Reproduction: asexual and sexual.

Examples: yeast, mold, and fungus.

Kingdom Protista (protozoa)

Domain: Eukarya.

Cell type: eukaryotic cell.

Cellular Organization: Mostly unicellular.

Nutrition: heterotrophs – autotrophs.

Reproduction: mainly asexual.

Examples: protozoa and amoebas.

Kingdom Archaea (Archaea)

Domain: Archaea.

Cell type: prokaryotic cell (does not have a nucleus) and with a cell wall without peptidoglycan.

Cellular organization: unicellular.

Nutrition: autotrophs – heterotrophs.

Reproduction: by binary fission.

Examples: methanogens and thermophiles.

Kingdom Bacteria (bacteria)

Domain: Bacteria.

Cell type: prokaryotic cell (contains no nucleus) and with a peptidoglycan cell wall.

Cellular organization: unicellular and colony formation.

Nutrition: autotrophs – heterotrophs.

Reproduction: by binary fission.
