SAS#4 Flashcards
Prokaryotic cell reproduction is with simple when compared with eukaryotic cell division.
Prokaryotic cells reproduce by a process known as
BINARY FISSION
Before a prokaryotic cell can divide in half, its chromosome must be duplicated a process known as
DNA REPLICATION
The time it takes for binary fusion to occur is called the
GENERATION TIME
The science of classification of living organisms
TAXONOMY
Taxonomy consists of three separate but interrelated areas:
CLASSIFICATION
NOMENCLATURE
IDENTIFICATION
Is the arrangement of organisms into taxonomic groups on the basis of similarities or relationships
CLASSIFICATION
Taxa include
KINGDOMS OR DOMAINS
DIVISIONS OR PHYLA
CLASSES
ORDERS
FAMILIES
GENERA
SPECIES
Is the assignment of names to the various taxa according to international rules
NOMENCLATURE
Is the process of determining whether an isolate belongs to one of the established name taxa or represents a unidentified species
IDENTIFICATION
An organism’s complete collection of physical characteristics is known as the organisms
PHENOTYPE
Kingdom system of classification, in which all organisms are placed into five kingdoms
KINGDOM PROKARYOTE
KINGDOM PROTISTA
KINGDOM FUNGI
KINGDOM PLANTAE
KINGDOM ANIMALIA
Late 1970 s, carl r. Woese device a
THREE DOMAIN SYSTEM OF CLASSIFICATION
In this three domain system there are
TWO DOMAINS OF PROKARYOTES
ONE DOMAIN EUKARYA
Bacteria and archaea are in the
KINGDOM PROKARYOTE
Algae and protozoa are in the
KINGDOM PROTISTA
