Pranav: As you can see in the picture, the
sun's energy is absorbed by the plant, because
of the chlorophyll in the leaves.
The plant gives out oxygen that humans and
animals need and the plant takes in carbon
dioxide, which is given out by humans and
animals.
The roots of a plant take in water from the
soil.
Sandeep: Step 1 - Roots absorb water and water
goes to the leaves through Xylem.
At the same time, the chlorophyll makes the
sun rays chemical energy.
Step 2 - Pores called stomata take in carbon
dioxide.
Step 3 - The chemical energy breaks the water
into hydrogen and oxygen atoms.
Aditya: Step 4 - Mixing the hydrogen and oxygen
atoms together with the sun's energy, the
plant makes a sugar called glucose, which
it eats for food.
Step 5 - The remaining hydrogen and oxygen
atoms become water and provide extra growth
for the plant.
Vihan: Photosynthesis is the process that
helps us live.
Aditya: Without it, plants would not be able
to survive, and because plants are producers,
other animals and humans won't be alive either.
Vihan: The plant uses carbon dioxide in the
air around it and water from its roots, when
the soil absorbs it, and makes a green pigment
called chlorophyll.
Chlorophyll takes sunlight and stores it as
energy during the process of photosynthesis.
Stanley: This is why when the hours of sunlight
become less, trees start preserving chlorophyll
for the next season, which makes leaves change
color.
All in all, photosynthesis is an important
process which helps all of us survive.
