are starting chapter photosynthesis in
that we are studying topic factors
affecting photosynthesis the factors
affecting photosynthesis or the process
of formation of food of glucose
formation are light intensity amount of
oxygen amount of carbon dioxide and
increasing temperature.
Photosynthesis photosynthesis can be
affected due to various businesses the
four main important processes that
affect or that can hamper the process of
photosynthesis are the amount of light
or intensity of light the amount of
carbon dioxide or co2 present the amount
of oxygen or o2 present and lastly the
temperature at which photosynthesis is
taking clicks for photosynthesis to take
place the optimum temperature would be
ideally about 20 to 35 degree Celsius if
in rainy ask or when the Sun is very low
or during winters the rate of
photosynthesis could be hampered even in
there is a decrease in if the
temperature goes about 40 degree Celsius
it can affect the rate of photosynthesis
ticket at such high temperatures
photosynthesis will take place slowly
because the rate of transpiration or
water loss will be higher
second intensity of light or amount of
light if there is increase intensity of
light then the photosystems both pigment
system-1 and pigment system too will
absorb sunlight and pass the sunlight or
photons in the form of electrons to
various electron acceptors at a faster
speed now doing photosystems the blue
and the green spectrum or you can see
the violet spectrum of the vapir region
is most of some or more shoots as a sun
source of energy the amount of carbon
dioxide now if we talk about the two
enzymes using photosynthesis IBP and PEP
re the peach can absorb carbon dioxide
only if it is present upto certain
limits whereas PEP
phosphine on pyruvate carboxylase can't
absorb lower limit of carbon dioxide and
if the intensity of carbon dioxide
decreases then it may affect
photosynthesis last one is oxygen now
oxygen is a byproduct during the process
of photosynthesis but in certain process
of photosynthesis given oxygen is
required so if there is increase amount
of
surgeon which is present during
photosynthesis it is called as Banville
effect and this increase amount of
oxygen can hamper the electron acceptors
factors affecting photosynthesis
the first factor affecting
photosynthesis is light the intensity of
light if it increases it can hamper the
process of photosynthesis blue violet
and red spectrum or photosynthesis is
said to be best for the process of
photosynthesis
the other factors that affect the
process of photosynthesis are
temperature carbon dioxide oxygen and
water temperature the optimum
temperature that is required for the
process of photosynthesis is
approximately 25 to 35 in these sensors
or 20 to 35 min sessions temperature
beyond that can cause transformation or
loss of water carbon dioxide now carbon
dioxide is the main product that is used
during the process of photosynthesis
high densities of carbon dioxide help c3
plants or and c4 plants to carry out
photosynthesis in a better way and we
all know c4 plants are nothing but
camtonz there's a DIC plants plants
which grow in deserts and c3 plants are
plants which can tolerate high temperate
environment or temperate Sun the amount
of oxygen can be inhibitory for the
process of photosynthesis if there is
increased amount of oxygen it can hamper
for the synthesis when a lot of oxygen
increases the rate of decrease in
photosynthesis is termed as one bird
effect and this is mostly seen in some
death plants which l0 fighting even in
hydroponic plants Hydra fighting plants
are nothing but water plants less water
can hamper the process of photosynthesis
directly we all know the equation of all
assistance starts with carbon dioxide
plus h2o and if there is less water
obviously the process won't stand
students in this part of the chapter we
have studied what well the five factors
that affected photosynthesis and if one
of the five factors is not working
properly the process of photosynthesis
could be stopped or slowed I hope you
are clear with the concept of factors
affecting photosynthesis
thank you
