Domains and Kingdoms Flashcards
(11 cards)
What are the three domains of life?
Bacteria, Archaea, Eukarya
Bacteria are prokaryotes with peptidoglycan walls, Archaea are prokaryotes in extreme environments, and Eukarya are organisms with nuclei.
List the six kingdoms of life.
- Bacteria
- Archaea
- Protista
- Fungi
- Plantae
- Animalia
Each kingdom has unique characteristics that define its organisms.
What is a defining characteristic of Bacteria?
Prokaryotic, simple, diverse environments
Bacteria are known for their simplicity and adaptability to various environments.
What are the specific traits of Archaea?
Extremophiles, ancient lineage
Archaea thrive in extreme environments and have an ancient evolutionary history.
What types of organisms are included in the kingdom Protista?
Phytoplankton (plant-like) and zooplankton (animal-like)
Protists can be unicellular or simple multicellular organisms.
Describe the structure of fungi.
Made of hyphae and mycelium
Fungi play a crucial role as decomposers in ecosystems.
What type of organisms does the kingdom Plantae include?
Photosynthetic, cellulose walls
Plantae includes a range from algae to flowering plants.
What are the two main groups of animals?
- Invertebrates
- Vertebrates
Invertebrates include sponges, cnidarians, worms, mollusks, arthropods, echinoderms; vertebrates include fish, amphibians, reptiles, birds, mammals.
Fill in the blank: The kingdom Fungi is characterized by _______.
decomposers, chitin walls
Fungi are essential in nutrient cycling and decomposition.
True or False: All organisms in the kingdom Animalia have cell walls.
False
Animalia is heterotrophic and does not possess cell walls.
What is the range of plant types in the kingdom Plantae?
Algae → mosses → ferns → gymnosperms → angiosperms
This range illustrates the diversity of plants from simple to complex forms.
