Classification of Living Things: Domains & Kingdoms

Classification of Living Things: Domains & Kingdoms

How do we identify living things?

Classification of Life

• There are 8 levels of classification.

• Domain is the largest and Species is the most specific.

3 Domains of Life

3 Domains

• There are 3 Domains: Bacteria, Archaea, and Eukarya.

• Domains have the largest differences among organisms.

Prokaryotes vs. Eukaryotes

• Prokaryotes are single-celled organisms that do not have a nucleus in their cells.

• Eukaryotes are made up of cells that have nuclei in their cells and a membrane to contain their organelles.

• Eukaryotes cells are usually bigger than prokaryotes.

Multiple Choice

What are the three domains we find in biology?

• Archaea, Bacteria, Eukarya

• Protista, Eubacteria, Animalia

• Archaea, Eubacteria, Eukarya

• Prokarya, Bacteria, Archaea

Multiple Choice

Which one of the following is the most general category of living things?

• Kingdom

• Domain

• Phylum

• Species

Multiple Choice

Prokaryotic cells do not have…….

• membrane bound organelles

• cell membrane

• DNA or RNA

• life

Multiple Choice

Which does only eukaryotic cells contain?

• nucleus

• DNA

• cell membrane

• ribosomes

Bacteria

• This domain is also the kingdom for these living things.

• Bacteria are made up of prokaryotic cells (single-cell/no nucleus).

• Can live in almost any environment.

Archaea

• This domain is also the kingdom for these living things.

• Archaea are made up of prokaryotic cells (single-cell/no nucleus).

• They have different genetics and cell walls than bacteria.

• Live in the most extreme environments.

Bacteria & Archaea

Eurkarya

• This domain splits into 4 different kingdoms: Animalia, Plantae, Fungi, and Protista

• They are made up of eukaryotic (complex, the nucleus in the cell).

• Can be single-celled or multicellular.

Multiple Choice

What do the domains Bacteria and Archaea have in common?

• They both have a nucelus

Multiple Choice

What makes the domain Eukarya unique?

• All organisms in this domain are multicellular
• All organisms in this domain reproduce sexually
