Advanced videos. hello students today we
are studying chapter diversity in
organisms in that we are studying topic
the meaning of systematics and taxonomy
both this term systematic and taxonomy
 and closely related about
Pittacus fighting and classification we
all know that before classifying
organisms we have to identify whether
they are living nonliving and then we
have to name them today we'll be
studying how taxonomy and systematics is
related to each other and to fighting
them classification .
systematics when I talk about
systematics and taxonomy
they both are correlated with each other
if you identify on organism and this
organism is living we need to understand
that what and how this organism was
diverse or was present systematics is
nothing but it is studying phylogenetic
relationship between different organisms
when I say phylogenetic relationship
example there is a relationship between
gorillas and human being and between
Ecola ecoli is an organism but the
common link between the three of them is
the chromosomal structure obviously the
genetic material of e.coli and human
beings are more similar we both are
eukaryotes so systematics is nothing but
the study of the diversification of
living forms both past as well as
present living organisms this
relationship among them through time
when it is studied it is called as
systematics basically systematics help
evolutionary studies to happen it helps
down to lay a crown for phylogenetic
studies the relationship between
organism and common example of
systematic study would be the
relationship between either leopard lion
and cat they all belong to the same
species of family in systematics after
we have read systematics for a
particular filer or particular species
then the time comes for name we all know
about binomial nomenclature that was
done by colonies now taxonomy is nothing
but meaning but during taxonomy what we
do is we name the organism we describe
the organism and then we classify the
organism basically you do not mean
clincher and then you classify the
organisms depending upon their mode of
nutrition their hereditary
characteristics whether their autotrophs
or chemoautotrophs whether they are
mighty cellular or unicellular their
phylogenetic tree is their evolutionary
traits and so on so whenever Whitaker
studied on organism the first step that
he took was to do systemic status to
identify the relationship between
various examples of organisms for
example if we talk about bacteria the
all half of phylogenetic relationship
they all are prokaryotes they all have
flagella
they can reproduce sexually as well as a
sexually and believe me so once Whitaker
did the systematic studies of bacteria
the next step what I did was the naming
some bacteria are gram positive and some
was gram negative this was taxonomy
basically naming and once naming was
done what did it was classification
classifying them into different groups
systematics systematics is nothing but
study of diversification of your organs
for example microbes humans plants
they're all a living but they have
different categories microbe is a
prokaryote whereas we humans and glands
are you gave us so systematic is
basically the study of that both past
and present organisms and the
relationship are studied in systematics
for example a key bacteria or you can
say you bacteria how it was related to
other forms of bacteria like e-coli
which is present today systemic also
leads to the study of how in evolution
the organisms changed for example how we
as humans lost our tail or was finding
fame in it that is a systematic study
during systematic study what happens is
we get to know the ancestors
relationship between organisms like me
and gorillas we are ancestrally related
in a system like systematics helps to
find evolutionary connect with your
organism how algae bacteria evolve and
now we have equalized zero one four five
the journey of microorganisms helps to
study systematics
taxonomy taxonomy is nothing but the
process of naming it means the process
of killing binomial nomenclature or
giving species name and general name to
an organism guy Linnaeus when gave
binomial nomenclature taxonomy is one
part of that upon some naming exogamy
believes in describing organism students
in this part of the chapter we have
studied about systematics and taxonomy
and how they are interrelated with each
other
if systematics is not an taxonomy cannot
be done in order to lay a ground for
studying an organism the first step is
identification that is living and
non-living second step is systematic
study the changes or evolutionary
changes of that organs and the third
step is naming and classification which
combines taxonomy I hope you are clear
with this concept thank you
