students today will be studying chapter
Plant Growth and development in that we are
studying topic factors effecting growth
of the plant water nutrients oxygen
temperature hormones these are the
factors that affect or stop or cheese
plant growth which will be starting
today.
factors affecting growth of fist is nutrient
imagine if your mom doesn't gives you
food for a week or for a day what will
happen you will not get energy in
stacked crime or housing similar is with
plants if plants get nutrients in
sufficient quantity they'll grow fast
but if plants don't get nutrients
insufficient contrary that growth will
cease or stop so a sustained supply of
nutrients is necessary for plants this
nutrients has to be vitamines and
minerals soil all the sources next is
oxygen if you don't eat what will happen
you will turn blue and die invention
similarly the plants need oxygen for
respiration remember photosynthesis
oxygen plays very important role in
photosynthesis next is what our body is
made up of 90% water so plants won't
need water yes they will plants need
water for all the metabolic activities
for all the cellular reactions whether
it is catabolism of catabolism
temperature now the ideal temperature to
grow a plant would be 25 to 30 degrees
sensors if you are in a state like
Maharashtra but if you go to Kashmir
it could be below for 225 degrees
Celsius
depending upon the place like now life
does not affect directly the kind of
growth but the intensity of flight the
quality of life the place where the
plant is kept and the duration of flight
effects land growth for example if you
keep a potted plant in your house in
that it will grow slowly it will take
its own sweet tangible there is a time
in the field will grow rapidly because
Sun is directly present over there
the last one growth hormones now growth
hormones hormones hormones are present
inside your body also similarly glands
also have growth hormones and this plant
hormones can either decrease plant
growth or increase plant growth for
example cytokinin a type of a hormone
any shaped cells emission where as given
in causes cell
there is a hormone called as excessive
acid which causes falling of links or
sentience in terms
[Music]
factors affecting tango there is a
factors affecting what it means this
parameters or this factors are important
to plan go and if any one of them misses
the plan will not go or the plan growth
will be reached and this factors are
nutrients now climb for the growth you
get all the essential nutrients from
soil whether it is minerals nitrogen
sulphur all of them a sustained supply
of essential nutrients is necessary for
plant growth depending upon the plant
the nutrients may change but all plants
need nutrients for the truth next is
oxygen oh you only doxygen to press file
similarly plants rest by with help of
oxygen or photosynthesis yes the process
to prepare time food is dependent on
oxygen children what for h2 it is
necessary for all the metabolic
activities of plant whether it is
catabolism and anabolism or any activity
in done is dependent on water or h2
your body needs what 95 percent of human
body is made up of water so glands would
need water yes they do need not
the next factors which affect plant
growth are temperature growth occurs in
the range of 25 to 35 degrees just
include temperate climate but if you
grow in cold weathers the temperature
can lie between 4 to 4:30 researchers
depending upon the plant for example in
Rajasthan the temperature would touch a
both have 30 degree sessions and cactus
is fine with that temperature but then
you go an apple in Kashmir it cannot
survive in 35 degree Celsius temperature
it means lower temperature light now
when you keep a plant in light it grows
faster experiment which was studied in
lower classes so light is essential for
further growth of the plant and plant
growth is influenced by intensity that
is amount of light that you put and the
duration of light that will keep the
plant entities lastly growth hormones of
plant hormones growth hormones are
enzymes that influence plant activity 5
to 4 months while they're called fight
over months phyto means plant and
hormones are enzyme set up producing
plants fight the hormones like cytokine
death help in cell division so students
in this part of the chapter we have
started the various factors that affect
tango I hope you all are clear about
this factors and the way they affect
plant growth thank you
