Photosynthesis
and
Cellular Respiration
What is Photosynthesis?
• The process by which plants, algae,
and some bacteria use sunlight,
carbon dioxide, and water to make
sugar.
• Happens in Chloroplast!
• Chlorophyll is the main pigment used
in photosynthesis.
• Photosynthesis occurs in
chloroplasts!!
• Plants use the energy captured by
chlorophyll to change carbon dioxide
and water into food.
• This sugar is then used as energy by
plant’s cells.
Photosynthesis
• Chemical Equation:
Here’s a trick to help you remember:
Can William Eat Giant Oreos?
Photosynthesis
carbon dioxide and water + SUNLIGHT
-----------------
glucose (sugar) and oxygen
What is Cellular Respiration?
• The process by which cells use
oxygen to break down sugar to
form energy.
• Cellular respiration happens in the
MITOCHONDRIA!!
Chemical Equation for Cellular Respiration:
• Here’s a trick to help you remember:
• Giant Oreos Come With Apple Sauce
Cellular Respiration
glucose (sugar) and oxygen ------------
-----
carbon dioxide and water ATP
(energy)

• Reactants
What’s needed before
the reaction can begin
(what do you need to
make a cake?)
• Products
End result of reaction
(what comes out of the
oven?)
Does this help?
• Chloroplast - the
organelle or cell part
• Chlorophyll - the green
“disk” uses sunlight to
create sugar
