who grouped all living things into kingdoms,
such as the animal and plant kingdoms
CAROLUS LINNAEUS
proposed a definition of the term species
ERNST MAYR/ THEODOSIUS DOBZHANSKY
referred to as the _____ species
concept
BIOLOGICAL
they are actually a group of organisms
that can interbreed and produce
fertile offspring in the natural
SPECIES
what animals can breed with their own kind
CHEETAHS/ MONARCH BUTTERFLIES
advocated by many scientists like Jean-
Baptiste Lamarck, Charles Darwin, and
Ernst Haeckel
PHYLOGENETIC SPECIES
phylogeny is the evolutionary history of a
certain species
PHYLOGENY
classifying organisms based not only on
physical similarities but also on their
ancestry and descent
PHYLOGENETIC SPECIES
the field of taxonomy that deals with identifying the
evolutionary relationships among the many different kinds of life on Earth, including extant and extinct proposed by Charles Darwin in his on the
Origin of Species
PHYLOGENTIC SYSTEMATICS
proposed by Charles Darwin in his On the
Origin of Species
TREE OF LIFE
used as an analogy to demonstrate that
all species originated from one or two
species

even the person who first identified
the organism
BINOMIAL NOMENCLATURE
_____ and _____ proposed a
third domain of life that led to the
development of a new six-kingdom system
CARL WOESE / RALPH S WOLFE
Carl Woese & Ralph S. Wolfe proposed a
_____ that led to the
development of a new _____
THIRD DOMAIN OF LIFE/ SIX KINGDOM SYSTEM
animals, fungi, plants, protists
EUKARYA
bacteria-like organisms living in
extreme environments
ARCHAEA
true bacteria
BACTERIA
the Domain is the highest taxonomic group, before the kingdom group
living world divided into three domains
SIX KINGDOM SYSTEM
3 domains =
2 PROKARYOTIC
1 EUKARYOTIC
adopted to reflect the difference between
bacteria and archaea
_____ was divided into two distinct groups
BACTERIA/ ARCHAEA/ MONERA
true bacteria and cyanobacteria
EUBACTERIA
bacteria-like organisms in extreme
environments
ARCHAEA
The living world is so diverse to the
point that it’s quite impractical and
impossible to enumerate each one of
the millions of classified organisms.
WAAAW
most diverse and widespread among
the prokaryotes
KINGDOM EUBACTERIA
unicellular that group together as
visible clusters of individual bacterial
cells (colonies)
KINGDOM EUBACTERIA
they reproduce asexually
KINGDOM EUBACTERIA
producers, consumers, and
decomposers
KINGDOM EUBACTERIA
_____ have ability to
cause diseases
BACTERIAL PATHOGENS
secrete proteins that attack
white blood cells
BACTERIAL PATHOGENS
_____ bacteria help digestive system
break down sugars
_____ into lactic acid
GOOD/LACTOSE

organisms based on mode of
nutrition
cyano bacteria are

sewage so that the waste can be
used again as _____.
FERTILIZER
first discovered in 1983 when
scientists took samples from a hot
vent on the floor of the Pacific
Ocean
KINGDOM ARCHAEA

KINGDOM ARCHAEA
Archaea comes from the _____
word archaios, which means
“ancient” or “_____.”
GREEK/ ARCHAIOS/ PRIMITIVE
they have unique cellular
characteristics that allow them to
survive extreme environmental
conditions
KINGDOM ARCHAEA
anaerobic archaeans that release
methane as a waste product
METHANOGENS

sewage, and intestinal tracts of
humans and ruminants
METHANOGENS
kingdom eubacteria they generate products like
_____, _____, and _____
