Biodiversity Flashcards
What characteristics are used to classify organisms into phyla?
- Body symmetry
- presence or absence of a coelom
- vertebrae or invertebrate
- levels of organization
- body layers
- segmentation
- body covering
- apendages
Describe the MAIN characteristics of Eubacteria
Eubacteria:
includes all prokaryotes that have peptidoglycan in their cell wall. They are thought to be “more advanced” microbes. Carbon eating bacteria.
Describe the MAIN characteristics of Archaea.
Archaea:
the cells to which is believed all other life evolved from.
Live in Extreme temperatures. Includes prokaryotes with “distinct” RNA sequences and no peptidoglycan in cell wall. Heat loving microbes.
Describe the MAIN characteristics of Eukarya
Eukarya:
Includes ALL eukaryotes including animals, plants, fungi and protists. Multi cellular organisms.
Describer the MAIN characteristics of the kingdom Fungi:
Fungi:
Includes mushroom and other fungi, absorbs nutrients. heterotrophics
Describer the MAIN characteristics of the kingdom Plantae
Plantae:
Includes trees, grass and flowers. They make their own food though photosynthesis. Sessile (don’t move) autotrophs.
Describer the MAIN characteristics of the kingdom Animalia
Anamalia:
Includes snails, birds and mammals. multicellular or made of cells. Have to obtain their own food. (hunt, etc) heterotrophs
Describer the MAIN characteristics of the kingdom Protista
Protista:
They are organisms with just one eukaryotic cell. Examples: algae, kelp, seaweed. (occasionally provide food, shelter, a oxygen to numerous. They are not classified as plants, animals or fungus.

List an example of one or two MAJOR defining feature of Chordata.
Chordata:
- Bilateral symmetry
- endoskeleton
- specialized segmentation

- appendages
ex) all vertebrates
Define and provide an example of endoskeleton
Endoskeleton:
An internal skeleton, such as the bony or cartilage, skeleton of vertebrates.
ex)fish, birds, mammals
Define and provide an example of symmetrical
Symmetrical:
made up of exactly similar parts facing each other or around an axis.
ex) humans
Define and provide an example of Acoelomate.
Acoelomate:
An invertebrate lacking a coelom, a digestive cavity that is the only internal cavity.
ex) sponges, jellies corals
Define and provide an example of Polyp
Polyp:
A body form is sessile, elongated and hollow. Their lower end is attached to a substratum. their upper end is where the mouth and tentacles are located. Asexual (budding)
ex) Sea anemones, coral
Define and provide an example of Medusa
Medusa:
free swimming, bell-shaped with tentacles hanging down around a central mouth.
ex) jellyfish
Define and provide an example of Vertebrate, invertebrate.
Vertebrate:
Animal of a large group distinguished by the possession of a backbone or spinal column.
ex) mammals, birds, reptiles, fish, amphibians.
Define and provide an example of Segmentation.
Segmentation:
Division into separate parts or sections.
ex) segmented worms, chordata, crustaceans
