|What in an easier way does it mean photosynthesis?
And how does water help?|
|Question Date: 2018-05-15|
Photosynthesis is the way plants get
energy. You and me eat food to get energy,
but plants capture sunlight and use that to
create energy. This creation of the energy
from light is called photosynthesis. The
plants combine carbon dioxide, water, and light
to create energy. The carbon dioxide come
from the air, the water comes from the ground
where the plant's roots suck it up from the soil,
and the light comes from the sun. The plant needs
all three of these things to create energy through
a chemical reaction that creates sugar
and oxygen. The plants use the sugar for
energy and the oxygen is released back into the
air around the plants.
Photosynthesis is what makes our lives
The source of almost all that energy is the
sun. Puny animals like us can't use the sun's
energy directly, we need plants to turn that
energy into food. Photo (light) synthesis
(making) basically means making food from the
energy in the form of light.
So photosynthesis means plants taking gas
CO2 (carbon dioxide)from the
atmosphere, and water (H2O) to
make make sugar
(C6H12O6) and re
lease oxygen (O2) as a by-product. In
order to do this "food", the plants need energy,
and this is the energy that comes from the light
(photons). This light is captures by pigments in
the plants, like chlorophyll ; the stuff that
makes plants green.
How does water help? Well, in order to
make food, the plants need both, gas
CO2 (carbon dioxide)from the
atmosphere, and water (H2O).
Then water is a fundamental component to perform

The word "photosynthesis" has two parts
to explain its meaning. The first part,
"photo", means "light". The second part,
"synthesis", means "the process of parts coming
together". The word in its entirety means, in
the context of biochemistry, "the process of
things coming together as a result of the action
of sunlight". To put it simply, the word
"photosynthesis" describes the set of chemical
reactions that allows plants, some algae, and some
bacteria to use sunlight as energy to drive the
making of important nutrients.
Water is required in photosynthesis as a
reactant , which is a word that describes
things that are required at the start of a
chemical reaction. The entire process of
photosynthesis uses water and carbon dioxide to
make sugar and oxygen. Sugar is something
plants need to store energy, so photosynthesis is
All living things need energy to grow. Humans
get energy from the food that we eat, but
plants get energy directly from the sun.
Plants do this by using the energy from the sun to
build sugar molecules that the plant uses for
energy or stores for later. The process by
which a plant uses energy from the sun to build
sugar molecules is called photosynthesis
(“Photo” comes from the Greek word for “light” and
“synthesis” means “putting together”).
Sugars are mostly made of carbon and
hydrogen atoms. The carbon for building the sugars
comes from carbon dioxide (CO2)
that plants absorb from the air. The hydrogen
comes from water (H2O).
A plant’s leaves work like solar panels
that you might see on the roof of people’s houses.
The absorbed light is used to remove an
electron off of a pigment molecule in the plant’s
leaves. In a solar panel, these electrons are
used to generate an electric current that
supplies electricity to the house. In plants this
electron is used to split a water molecule into
hydrogen and oxygen. The oxygen is release into
the atmosphere and the hydrogen is eventually used
to build the sugar molecules.
