Biology Domains and Kingdoms Quiz

Study Notes

Domains

Taxonomic category above the kingdom level, consisting of three domains: Archaea, Bacteria, Eukarya.

Archaea

Unicellular organisms that thrive in extreme environments such as volcanoes, Antarctica, and the deep ocean.
Considered one of the three domains, closely related to Earth's earliest cells.
Distinguished from Bacteria, as Archaea can survive in extreme conditions.

Bacteria

Unicellular organisms that live in normal environments.
Classified in the domain of Bacteria, known for not surviving in extreme conditions.

Eukarya

Can be unicellular or multicellular and inhabit normal environments.
Composed of eukaryotic cells, which are larger and more complex than prokaryotic cells and contain a nucleus.
Includes several kingdoms: Fungi, Plantae, Animalia, and Protista.

Kingdom Fungi

Decomposers that obtain nutrients from decaying organic materials.
Fungi are eukaryotic organisms that can be multicellular (like mushrooms) or unicellular (like yeasts).
Cannot move from place to place.

Kingdom Plantae

Consists of organisms known as plants, which are producers.
Capable of photosynthesis, allowing them to make their own food.

Kingdom Animalia

Comprised of consumers that eat food for energy.
Members are known as animals and are defined as eukaryotic organisms.

Kingdom Protista

Includes a diverse group of eukaryotes that can be either unicellular or multicellular.
Protists do not fit neatly into the other kingdoms and exhibit significant variability.

Additional Information

Kingdom Plantae is the only kingdom that contains organisms capable of producing their own food.
Domain Eukarya encompasses organisms including humans, cats, and birds, all of which are classified as eukaryotes.
