Diagrams
How do we organize organisms?
With Taxonomy
What are the three domains of life?
Archaea, Bacteria, and Eukarya
What is a eukaryotic cell?
Hint: State two things
A cell with a defined nucleus and membrane-bound organelles
What kingdom are mushrooms and mosses in?
Fungi
This kingdom contains both single-celled and multicelled organisms that have eukaryotic cells. All of the organisms in this kingdom are still fairly simple, consisting of one or many cells.
Protista
This type of diagram displays inferred evolutionary relationships among biological species based on similarities and differences in their physical and genetic traits
Phylogenetic Tree
This term refers to an organism that must consume other organisms for energy because it cannot make its own food
Heterotroph
what does ancestry mean?
The lineage of successive parents and offspring that leads to an organism or species
This group of bacteria is believed to be responsible for adding oxygen to Earth's atmosphere.
cyanobacteria
He was the first to attempt classification by grouping plants by size and animals by their location, such as land, water, or air
Aristotle
This branching diagram is used to represent a hypothesis about the evolutionary descent of groups of organisms from a common ancestor.
Cladogram
This term refers to the lineage of successive parents and offspring that leads to a specific organism or species.
Ancestry
A cell lacking a nucleus or any other membrane-enclosed organelle
Prokaryotic cell
What kingdom do methanogens belong?
Archaea
These tiny microorganisms live in ponds all over the world and are unicellular members of kingdom Protista
Paramecia
These specific points on a phylogenetic tree show where closely related organisms branched from their common ancestor.On a cladogram, each branch that is farther from the bottom represents a group that has more of these specific types of traits.
Scientists primarily use these three criteria to classify an organism into a specific kingdom?
cellular structure, number of cells, and mode of nutrition
What is kingdom?
The level of taxonomic classification beneath domain and above phylum and contains the greatest number of species and the highest biodiversity
Ancient organisms that live in extreme environments, such as deep-sea hydrothermal vents or places with very salty water, such as the Dead Sea or the Great Salt Lake in Utah.
Archaea
This Swedish botanist and doctor designed a system of classification in the 1700s that led to modern taxonomy and is still used today
Carl Linnaeus
On a cladogram, each branch that is farther from the bottom represents a group that has more of these specific types of traits.
Derived Traits
In multicellular organisms, these are cells that look different and are able to perform different functions.
differentiated cells
This term is defined by scientists as descent with modification from a preexisting species.
Evolution
Which two of the six kingdoms are prokaryotic (meaning their cells lack nuclei)?
Archaea and Bacteria
This Filipino-American scientist studied cyanobacteria and extremophiles in Antarctica, providing a basis for searching for life on Mars
