sunlight energy is used
to make glucose.
next
What type of organisms
perform
Photosynthesis?
$400
$200
Plants
(Producers/Autotrophs)
next
Where in the cell does
Photosynthesis take
place?
$300
The Chloroplast
next
What is the ultimate
function of
Photosynthesis?
$400
To make food
(glucose/sugar) for
plants.
next
What does the word
“Photosynthesis” mean?
$500
“Making from sunlight”
next
What are the 3
reactants of
Photosynthesis?
$100
1. Carbon dioxide.
2. Water
3. Sunlight
next
What are the 2 products
of Photosynthesis?
$200
Glucose & Oxygen
next
What type of energy
does the plant use to
convert carbon dioxide
and water into sugar?
$300
Sunlight (light energy)
next
What is the simple
chemical equation for
Photosynthesis.
$400

C6H12O6 + O2
next
Write the complex
chemical equation for
Photosynthesis.
$500
6CO2+ 6H2O + sunlight
 C6H12O6 + 6O2
next
All energy on
Earth comes from
the…
$100
Sun
next
How do plants get their
energy?
$200
By making their own
food (sugar) using
sunlight, carbon dioxide
and water.
next

next
What is the difference
between autotrophs and
heterotrophs?
$400
Autotrophs – are plants that
make their own food.
Heterotrophs – are animals
that must consume other
organisms for energy.
next
