The photosynthetic process occurs
only in the chloroplasts,
tiny subcellular structures
contained in the cells of leaves and
green stems. In photosynthesis, the
sun’s energy combines hydrogen from
water (H20)
with carbon dioxide (CO2)
turning them into carbohydrates.
Oxygen (O2)
is given off as a by-product of
photosynthesis. The chemical
equation for the process of
photosynthesis is: 6CO2
+ 6H20
+ light C6H12O6
+ 6O2
This process is directly
dependent on the supply of water,
light and carbon dioxide. Any
one of the factors
on the left side of the equation
(carbon dioxide, water, or light)
can limit photosynthesis regardless
of the availability of the other
factors. If any one of these factors
is limiting, then the whole process
slows down or stops. An implication
of drought or severe restrictions on
landscape irrigation is a reduction
in photosynthesis and thus a
decrease in plant vigor.
In a tightly closed greenhouse
there can be very little fresh air
infiltration and CO2
levels can become limiting. This in
turn limits plant growth because the
production of sugars needed to do
the work involved with growing is
limited. Many greenhouses provide
supplemental CO2
to stimulate plant growth.
The rate of photosynthesis is
somewhat temperature dependent. For
example, with tomatoes, when
temperatures rise above 96 degrees
Fahrenheit the rate of food used by
respiration rises above the rate
that food is manufactured by
photosynthesis. Plant growth comes
to a stop and produce loses its
sweetness.

when plants give the light from sun .this process called photosynthesis.
we give them water, sun light in this way plants make their own food.
IN this way serve food their all parts .
exp: root ,leaf.
