Now the last video we have studied
about the process of Mitosis what are
the two I will repeat once again what
are the stages of Mitosis then I will
teach you were significance of mitosis
status importance of mitosis now
speaking about stages of mitosis, mitosis
consists of or carried out in two major
stages first it's called as Karyokinesis
and the second stage is called as
Cytokinesis that's making our
Karyokinesis what is meaning of
karyokinesis it means division of
nucleus and what Cytokinesis answers it is
a division of cytoplasm now division of
nucleus is not as simple as Cytokinesis
 that is why division of nucleus is
carried out in four strips first
prophase that is a longest phase which
consists of earthly and wheat phases
fissures
next is metaphase which is also called
as middle fields of middle stage next is
anaphase anaphase is a short taste face
and the last one is Pino phase does the
terminal phase til O stands for terminal
after telophase cytokinesis and then
this is divided into two not speaking
about mitosis mitosis as equation or
diffusion never forget that now what is
the meaning of equation deviations it
creational division doesn't means that a
servant should get equally divided it is
considered but the most important thing
in equation a division is that the
content of chromosome remains the same
from mother cell to daughter's ship that
is the most important part of my process
been called as equation divisions now we
are going to study significance of
mitosis or importance of mitosis how
mitosis is important in our life all we
can say what are the advantage of
mitosis for our bodies so let's start
with the first significance we must be
knowing this thing when
we're born your height and weight was
less compared to right now what your
body is so when you were born the cell
started dividing and your body grew at a
greater certain height and also you
gained some weight how is it possible it
is possible because of cell division so
first thing which happens because of
mitosis is good next is dripping the
second significance of importance of
mitosis is repair or we can say healing
how mitosis helps in repair and healings
when you the clean event whenever you
got hood or you got bruised then you had
a stretch mark and also stuff and that's
nice mom doesn't remain throughout your
life after sometime what happens to the
wound or bruises of your body it gets
cured how it gets killed because one
hard layer is formed on the surface of
your bruise of wounds and that process
and the process by which that surface is
formed is called as cell divisions if I
speak specifically that the process is
called as blood clotting so blood
clotting helps in healing and repairing
the Bulls cuts or the injury caused to
our body next significance is
replacement now you must be knowing this
thing student red from birth till death
every organisms body some part of the
body or some part of the cell or tissue
get fractured and it needs to be
replaced by some other since so this
process is also carried out by the
process of mitosis
one example is of RBC the lifespan of
RBC RCC is the most important cell of
your
I hope you know that why it was most
important because it carries oxygen to
every cell of the body without RBC also
of your body that is 100 trillion cells
may die that is why this is the most
important cell in our body now speaking
about RBC what RBC have how much life
span it has life span of 120 days
so once the 120 days is completely now
what then the process of cell division
is carried out in bone marrow and the
next set of RBC's are formed so this is
how the bone out of the used RBC are
replaced by the new RPC the process is
called as replacement and what actually
happened over there is say division and
that is mitosis mitosis also helps in
the process of reproduction now you must
have learned this thing in the first
chapter there are two types of
reproduction a section and section
speaking about a section in case of a
section there is a process which is
commonly known to everybody carried out
by amoeba that is binary fission so
binary fission is nothing but the
division of tips it also speaking about
East is to also carry out mitotic
division so in case of a section when
unison organism is dividing and
producing two organism of the kind then
actually cell division is taking place
that is in a section what about sexual
in case of section also mitosis is
helpful it helps in increasing the
number of a count of sperm I hope you
know into ml of semen there should be
400 millions form so from once formatted
cells source forms are form and then
they keep on dividing to form millions
of sports
the next stage of that spawn formation
is nothing but mitosis which will study
in detail in meiosis process so we next
and the last significance is
reproduction you will be completed with
the significance of my daughter student
thank you very much
