1a What are the six kingdoms of life as they
are now identified? The six kingdom system of life includes the
kingdoms of Eubacteria , Archaebacteria , Protista , Fungi , Plantae
b Why did systematists establish the domain?
They wanted to name all known organisms living and extinct toward
the goal of systematics, they wanted to group things in a way that
reflects evolutionary relationships
c What were the Monerans? Monera include all
up to him and him Why did systematists split
them into two kingdoms? In the 1990s researchers learned a great
deal about the genetics of bacteria the organisms in the kingdom,
they were actually two genetically and biochemically different
groups so they are separated into two kingdoms eubacteria and
2a What are the three domains of life? Domain
bacteria , Domain archaea and Domain eukarva.
b Why are quotes used when describing the
quotes around “Protista” because this is a paraphyletic group
,it means that there is no way to put all unicellular eukaryotesn
into clade that contains a single common ancestor so you use
quotations to show that this is not a true clade.
c Do you think the tree of life cladogram will
always stay the same as it is in figure 1818 explain? No because
evolutionary classification is rapidly changing science as
biologists study relationships they change the way organisms are
grouped sometimes the names of organisms and their hypotheses about
relationships are not hard facts.
table compares some molecular characteristics of organisms in the
a interpret tables: Which domain have
unbranched lipids in their cell membranes? Bacteria and Eukarya have
unbranched lipids in their cell membranes.
b Interpret tables : Which domain has just one
type of RNA polymerase? Bacteria has just one type.
c Analyze data on the basis of this table how
are archaca different from bacteria? Archaea are different than
bacteria because bacteria has rare intrans and archaea have
sometimes present intrans, bacteria has one type of RNA and archaea
has several types of RNA, bacteria does not have histones found with
DNA and archaea has
hashistones found with DNA, and bacteria has unbranched lipids in
cell membranes and archaea has some branched lipid in cell
