3 domains of life include:
Domain Archae
Domain Bacteria
Domain Eukarya
Characteristics of Domain Archae:
1.) Prokaryotic
2.) Most ancient form of life.
3.) Live in extreme environments such as hot springs, deep sea vents, hyper-saline pools.
4.) 1 kingdom- kingdom archae.
Characteristics of Domain Bacteria:
1.) Prokaryotic
2.) Differ from Archae by habitat, structure of cell walls, and RNA structure.
3.) 1 Kingdom: Kingdom bacteria.
Characteristics of Domain Eukarya:
1.) Eukaryotic
2.) Contains 4 kingdoms:
-kingdom protista
-kingdom plantae
-kingdom fungi
-kingdom animalia
Domain Archae:
Kingdom Archae
Domain bacteria:
Kingdom Bacteria
Domain Eukarya:
Kingdom Protista, Kingdom Animalia, Kingdom Fungi, Kingdom Plantae.
Characteristics of Fungi and example:
1.) eukarya
2.) multicellular and Unicellular
3.) heterotroph (feed on growth)
ex: mushroom, mold, puffball
Characteristics of Protista and example:
1.) eukarya
2.) multicellular and Unicellular
3.) either heterotroph or autotrophic (produces its own food)
ex: kelp, amoeba
Characteristics of Plantae and example:
1.) eukarya
2.) only multicellular
3.) autotrophic (produces its own food)
ex: trees, flowers, grass.
Characteristics of Animalia and example:
1.) eukarya
2.) only multicellular
3.) heterotrophic
ex: tiger, giraffe, fish
Vestigal Structure definition and example:
-evolutionary lettaer
-evidence of its ancestory
ex: whale pelvis, appendix wings of flightless birds. eyes of cave dwelling fish.
Homologous Structures definition and example:
-structures similiar in form, may differ in function.
ex: forelimb of vertebrates.
Analagous Structures definition and example:
-similiar in function but don't share an evolutionary history.
ex: wings of birds, bats, insects.
Difference between Eukarya and Prokarya
Prokarya is single stranded and doesn't have a nucleus, Eukarya DNA is double helix and has a nucleus
Fungi are _______
Heterotrophic
Chinook Salmon belong to what kingdom?
Animalia
Coral belong to what kingdom?
Animalia
Amoeba belong to what kingdom?
Protista
Mold belongs to what kingdom?
Fungi
An example of a structure that's homologous with a human arm would be ________
Bat wing
What is a cladogram?
A diagram used to show relatedness
What is convergent evolution and give an example
Convergent evolution describes the acquisition of the same biological trait in unrelated lineages.
Ex: Bat and bee because they both have wings.
What domain and kingdom would an organism that is unicellular, eukaryotic, and photosynthetic belong to?
Domain Eukarya, Kingdom Protista
An organism that shares our class but not order would be ________
Whale
Why do we use scientific names?
Because local names conflict with other names.
Whats the small fleshy fin near the end of a fish called?
Adipose fin
