Taxonomy & Domains
The broadest and most general level of classification in taxonomy.
What is a Domain?
Considered non-living, these "hijackers" lack basic cellular structure and must invade a living host to reproduce.
What are viruses?
The process plants use to turn carbon dioxide, water, and sunlight into food (glucose) and oxygen.
What is photosynthesis?
The biological organization hierarchy for complex animals begins with Cells, moves to Tissues, then Organs, and finishes with this.
What are Organ Systems?
Birds and insects use these adaptations to fly, hover, and dive.
What are wings?
The scientific study of how living things are classified based on similarities in their DNA and structures.
What is taxonomy?
Single-celled prokaryotes that can be found almost everywhere and come in rod, spiral, or sphere shapes.
What are bacteria?
Small openings on the underside of leaves that allow gas exchange and prevent water loss.
What are stomata?
Animals with a backbone belong to this specific group.
What are vertebrates?
Octopuses use this adaptation to move quickly by pulling water into their body and quickly pushing it out.
What is jet propulsion?
These single-celled prokaryotes are famous for living in extreme environments like boiling hot springs and deep-sea vents.
What are Archaea?
Earth's natural decomposers, this Kingdom includes mushrooms, molds, and yeast.
What are Fungi?
The green pigment found inside chloroplasts that absorbs sunlight to drive photosynthesis.
What is chlorophyll?
A sea star (Starfish) features this specific type of symmetry, where body parts are arranged in a circle around a central point.
What is radial symmetry?
Mollusks use this specific muscular structure to crawl or glide.
What is a muscular foot?
Every organism in this domain has cells that contain a distinct nucleus holding its DNA.
What is Eukarya?
Known as the "odds and ends" drawer of classification, most organisms in this eukaryotic Kingdom live in moist or aquatic environments.
What is Protista (or Protists)?
The type of vascular tissue responsible for transporting water and minerals from the roots up through the stem.
What is xylem?
Amphibians and reptiles are classified as this, meaning they rely on outside sources like sunlight to stay warm.
What are ectotherms?
Whales, seals, and dolphins obtain their fresh water primarily from this.
What is the food they eat?
The correct hierarchical order of classification from broadest to most specific is Domain, Kingdom, Phylum, and these five remaining levels.
What are Class, Order, Family, Genus, and Species?
Bacteria move using tails called flagella and these tiny hairs.
What are pili?
Because they lack a network of vascular tubes and are only a few cell layers thick, this type of plant must live in moist environments.
What are nonvascular plants?
Marsupials finish development inside a pouch, while this group gives live birth after the embryo fully grows via a special organ.
What are placentals?
To conserve water, a reptile's kidneys pull solid waste out and do this to the leftover liquid.
What is reabsorb it?
