Answer:
The process by which
green plants make their own food in the form of glucose from CO2 and
H2O by using sunlight energy in the presence of chlorophyll, is
called photosynthesis.
Oxygen gas is
released during photosynthesis. It can be represented as.
The process
takes place in the green leaves of a plant glucose in the following steps
(i) Sunlight
energy is absorbed by chlorophyll (green pigment present in leaves).
(ii) This
light energy is converted into chemical energy.
(iii) Water
molecule is splatted into hydrogen and oxygen. Water required is taken from the
soil. It is transported to the leaves from the soil through the roots and stem.
The oxygen
gas produced as a byproduct goes into the air.
(iv) The
hydrogen released during the above reaction is utilized for reduction of CO2to
form carbohydrate (glucose) by utilizing the chemical energy. The CO2
enters the leaves from the air through tiny pores called stomata,
(v) The
extra glucose is stored as starch in the leaves of the plant.
