Classification & Taxonomy
This term refers to biologically meaningful groups at any level of organization.
What are taxa?
These are the only types of traits considered in cladistic analysis.
What are derived characters?
This domain contains organisms that live in extreme environments.
What is Archaea?
This molecule carries the instructions for making new viruses
What is DNA or RNA?
Most protists are this type of organism.
What are single-celled organisms?
Without gas exchange, plants cannot do this.
What is make food?
This naming system uses two names to identify a species.
What is binomial nomenclature?
A cladistic analysis shows this relationship among organisms.
What is relative relatedness among lineages?
These two domains contain only unicellular organisms.
What are Bacteria and Archaea?
This is the basic structure of a virus.
What is DNA or RNA surrounded by a protein coat?
Amoebas move using these structures.
What are pseudopods?
Land plants likely evolved from an organism similar to this.
What is green algae?
In scientific names, this part is always capitalized.
What is the genus name?
Similar DNA sequences in very different organisms suggest this.
What is a common ancestor?
Bacteria and archaea differ mainly in this cell feature.
What is the composition of their cell walls?
A lytic infection ends with this event.
What is the bursting of the host cell?
Protists exchange genetic material during this process.
What is conjugation?
This is the key difference between a sporophyte and a gametophyte
What is diploid vs. haploid life stages?
A monophyletic group includes this.
What is an ancestor and all of its descendants?
DNA from these two eukaryotic cell structures is used to study evolution.
What are the nucleus and mitochondria?
Prokaryotes survive harsh conditions by forming these structures.
What are endospores?
Viruses that infect bacteria are called these.
What are bacteriophages?
All fungi share this nutritional and cellular trait
What are heterotrophic eukaryotes?
This vascular tissue transports sugars produced in photosynthesis.
What is phloem?
This type of classification groups organisms based on common descent.
What is evolutionary classification?
This is why Protista is not considered a valid evolutionary kingdom.
What is that protists share closer ancestors with other groups than with each other?
These organisms can live with or without oxygen.
What are facultative anaerobes?
Viruses are considered nonliving because they cannot do this independently.
What is reproduce or carry out metabolism?
This evidence supports the idea that eukaryotes evolved from prokaryotes.
What is genetic and fossil evidence?
Seeds spread by animals are usually found in this type of fruit.
What are fleshy, nutritious fruits?
