What is Photosynthesis - Nutrition in Plants Video Lecture - Class 7

hi friends we are here today to learn
something about photosynthesis now look
at the beautiful leaf in the picture
Maya leaves important the leaves form
the important part of the plant as we
observe the leaves are so arranged on
the stem that they have been exposed to
sunlight they trap the sunlight and
convert it into compounds instead help
in the preparation of food the beautiful
chlorophyll molecule on the leaves
present are of course the basis of life
it is the light absorbing pigment in
green plants now we have a cross-section
of the leaf let's have a look at the
first part of it the top contains Placid
cells on the leaves upper surface which
receive direct rays from the Sun the
yellow and orange pigments which are
found are called catenoid pigments the
red and purple occur in the SAP of the
cells which are called anthem and the
kainalu the transparent waxy layer
admits sunlight while preventing
evaporation of water the vein support
the leaf and carry water to the leaf and
food back into the rest of the tree the
loosely packed cells
of course allow of carbon dioxide which
help in photosynthesis
mr. mater allows movement of air into
life
now what are the chief ingredients for
the preparation of food we have the
sunlight the carbon dioxide the oxygen
and water the leaf is responsible for
trapping the sunlight and converting it
into chemical energy in the Flom form of
glucose using carbon dioxide from the
atmosphere and water from the soil this
glucose is then transported to the other
parts of the plant
putting it into a simpler way this is
called photosynthesis
now what is photosynthesis
photosynthesis is a process by which
plants use the energy of sunlight to
produce sugar it is a process of
converting light energy into chemical
energy it primarily occurs in plant
leaves the stomata help in letting
carbon dioxide in and oxygen out the
mesophyll cells on the leaf have
chloroplasts and this is where
photosynthesis actually occur now water
is actually observed from the roots
which is carried to the leaves the
carbon dioxide obtained from the air
enters the leaves through Stamatis and
diffuses the cells containing
chlorophyll the green pigment instead
converts active energy into food that
can be spread to the later part of the
flower thus photosynthesis provides us
the necessary oxygen in order to breathe
we exhale the carbon dioxide the plants
give us plants have become crucial for
life and we rely upon him as a source of
food isn't it a very interesting lesson
about photosynthesis yes of course we
have a very important lesson to be
learnt from plants as plants are very
useful for for the survival of human
beings thank you
