Taxonomy Basics
This is the science of naming and grouping organisms.
What is taxonomy?
This domain includes single-celled organisms without a nucleus that often live in extreme environments.
What is Archaea?
A clade is a group of organisms that includes a common ancestor and all of its __________.
What are descendants?
This process explains how eukaryotes evolved when one cell engulfed another but both survived together.
What is Endosymbiosis?
On a phylogenetic tree, these points represent common ancestors.
What are nodes?
The broadest category in taxonomy, above kingdom.
What is Domain?
This domain consists of simple, single-celled organisms that are highly adaptable and play critical roles in nutrient cycling.
What is Bacteria?
This type of diagram shows evolutionary relationships with branches and nodes.
What is a phylogenic tree?
This organelle, originating from endosymbiosis, produces energy for the cell.
What is the mitochondrion?
A single “branch” that can be cut off with one snip on a tree represents this group.
What is a clade?
The sequence of levels in taxonomy from broadest to most specific.
What is Domain → Kingdom → Phylum → Class → Order → Family → Genus → Species?
This domain contains organisms with membrane-bound organelles and a true nucleus.
What is Eukarya?
Fungi are more closely related to this kingdom?
What are animals?
This organelle, found in plants, allows them to perform photosynthesis.
What is the chloroplast?
The order of evolutionary relationships shown on a tree is called this.
What is lineage?
The most specific taxonomic level that identifies a single type of organism.
What is Species?
Archaea are successful because they can survive in these unusual places, like hot springs and salt lakes.
What are extreme environments?
Plants are multicellular organisms that create food through this process.
What is Photosynthesis?
________ are multicellular or single cellular organisms with membrane bound organelles and a true nucleus.
What are Eukaryotes?
Studying clades and phylogenetic trees helps us protect this by understanding species relationships.
What is biodiversity?
The three domains of life.
What are Archaea, Bacteria, and Eukarya?
Threats to Bacteria include overuse of this type of medication.
What is Antibiotics?
Animals have specialized tissues, nervous systems, and this ability that helps them survive.
What is mobility?
Disruptions like disease, toxins, or climate change threaten this aspect of Eukaryotes.
What is homeostasis?
The Animal Kingdom shares a common ancestor with this kingdom, revealing their relationship on the tree of life.
What is Fungi?
