Photosynthesis and Cellular Respiration
PhotosynthesisThe process in
which organisms use water along with sunlight and carbon dioxide to make food
What performs photosynthesis?Autotrophs-an organism that can
“make” its own foodExamples of Autotrophs include:
Algae-a simple nonflowering plant that is often unicellular
Phytoplankton-microscopic plants that drift or float in the sea or in fresh water
And of course….PLANTS!
How does photosynthesis work?INPUTSSunlight- absorbed by chlorophyll6 Water Molecules
6 Carbon Dioxide Molecules
How does photosynthesis work?OUTPUTS1 molecule of Glucose6 molecules of O2
All together: Are both sides even for each element?

Written and Chemical Formula for Photosynthesis
Carbon dioxide + water+ sunlight glucose +oxygen
6CO2 + 6H20 + sunlightC6H12O6 + 6O2
Cellular Respiration
How glucose (a simple sugar) is broken down in the mitochondria for energy
Cellular Respiration occurs after photosynthesis
Powerhouse-Mitochondria break things down, like our digestive system
If we already have glucose, why do we need cellular respiration?
Glucose has to be broken down into ATP: an energy source that plants and humans can use
Glucose is stored until it’s needed!
Written and Chemical Formula for Cellular Respiration
Glucose + Oxygen Carbon Dioxide + Water + Energy (ATP)
C6H12O6+ 6O2 6CO2 + 6H2O + ENERGY (ATP)
Cellular Respiration: in plants and animals
Photosynthesis and Cellular RespirationPhotosynthesis releases oxygen
into the air so we all can survivePhotosynthesis also gives us
glucose when we eat a plantThis energy is then turned into a
usable form through cellular respiration
