Broad Classification of Animalia Video Lecture - NEET

hello friends this video on kingdom
Animalia part 9 is brought to you by
exam feel calm no more fear from exam so
let us now look at the classification of
the Animalia kingdom based upon whatever
we have discussed so far so this is my
annamaria kingdom now the first thing or
the first parameter that we discussed
was the level of organization right what
by the various levels that we discussed
cellular level tissue level organ level
organ system level right so now if you
consider the cellular level the cellular
level so what comes under cellular level
we will see that now if you talk about
the next parameter that we discussed
what was the next parameter that we
discussed it was symmetry now the
organisms which come under cellular
level they wear the poly fara now these
cellular level organisms wear a
symmetric right okay now these the third
thing that we talked about was Silom
that is the presence or absence of a
true coelom now these asymmetric animals
were also a celo mate
now what were these animals these
animals where Paulie fara
right now here let us see the rest of
the animals if you talk about the level
of organization the rest of the animals
were either tissue level or organ level
or organ system level of organization
like if you talk about symmetry
so symmetry when you talk about there
are three types of symmetry that we
spoke about asymmetry radial symmetry
and bilateral symmetry now if you talk
about the tissue level of organization
with a radial symmetry and talking about
the silom AC donate so tissue level with
radial symmetry is zero mate
what were they there Cillian traits so
this was the next final so if you
compare the first phylum poly fara with
the next phylum sale and trade Awadh you
see it has cellular level it has tissue
level is asymmetric it has radial
symmetric this is Islamic this is also
in solomid
so there were some improvements in
Saline traitor okay okay let's go to the
next one now if we talk about the
remaining types of level of organization
that is the organelle in the organ
system level so now these are the these
other organisms with organ or organ
system level of organization and with
bilateral symmetry so let us see what
all do we have there with bilateral
symmetry now with bilateral symmetry
again here we have three types depending
upon the type of serum that is they can
be a selamat they can be pseudo selamat
or they can be Salam lates so what are
they these were platyhelminthes
so this was a third phylum when you talk
about the pseudo Silla mates what were
these these where the nematodes the
fourth phylum if you talk about the celo
mates
now these see no means if you see they
are all CeeLo mates they all have organ
system level of organization they all
have bilateral symmetry so now you need
more parameters to classify them see how
were you able to classify them because
they differed in some of these some of
these three parameters but now you have
reached a point where they are not
differing in any of these parameters so
how are you going to define coming
characterize them okay so now we will
talk about the fourth factor which we
discussed that is segmentation right now
based on the type of segmentation which
is present we can again we again divided
them into different class so
segmentation present so they were known
as annelids
again segmentation present but the
segmentation the way type of
segmentation was different they were
known as our toe pots and for the rest
of them the segmentation was not present
so that is segmentation absent so what
were the rest of them which was left out
so we will take them here so
segmentation was absent so what why they
left out once left out once where the
mollusks so now we took into
consideration the fifth
parameter that is notochord the presence
or absence of notochord so now no to God
if you consider this note of God absent
in molluscs notochord is absent in
echinoderms and notochord is present in
cordons so this chart roughly tells you
that how these different parameters
which we have discussed so far
they were utilized to sub classify or to
classify the Animalia kingdom so where
we ended up we ended up in these ten
finer for a fairer salient raita
platyhelminthes nematoda annelids
Arthropoda it kind molluscs echinoderms
quadriga so these were some of the
kingdoms are some of the final some of
the important phylum under the animal
kingdom i mean i just tried to give you
an idea that why we discussed about so
many parameters why was not one
parameter sufficient to classify this
kingdom now i'm understood why we needed
so many factors to classify it because
there are so many organism so if you
just consider one factor you will see
that only a bunch of them will fall in
one category in the rest all of them
will follow the other category but when
you have so many different parameters to
classify them you can actually classify
them in a relatively better way so in
this lesson we are going to talk about
these different phyla under the animal
kingdom that is for affero salient rata
platy ailments
nematoda annelida arthropoda male star
echinodermata hey me more data and more
data so here by mistake it is protocol
data it should have been Hemi or data so
these are the ten phyla
which we will discuss in detail in this
lesson so we will start our discussion
with Bolivar so for we will go one by
one we will talk about each phyla we
will talk about all the characteristics
features examples of each file so that
is how I be able to proceed with this
lesson so that is the agenda of our
lesson hereafter thank you
