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.
