TRANSCRIPT
PhotosynthesisPhotosynthesis- A process by which plants convert sunlight, water, and carbon dioxide into food energy (sugar), oxygen and water.
ChloroplastChloroplast- An elongated cell organelle containing chlorophyll where photosynthesis takes place.
ChlorophyllChlorophyll- A green molecule which uses light energy from sunlight to change water and carbon dioxide gas into sugar and oxygen
RespirationRespiration- The process by which the chemical energy of "food" molecules is released and changed into ATP.
MitochondriaMitochondria- Rod-shaped organelles with a double membrane which converts the energy stored in glucose into ATP for the cell.
O2 + glucose H20 + CO2 + ATP

Do you notice something Do you notice something about this equation?about this equation?
Animals use: Sugar (from producers/plants) Oxygen (from producers/plants)
Plants use: Carbon dioxide (from animals)
Photosynthesis Equation:H2O + CO2 + lightlight O2 + glucose
Respiration Equation:O2 + glucose H2O + CO2 + ATPATP
What about What about light light && ATP? ATP?
The Law of Conservation of Energy says…
1.) Energy cannot be created2.) Energy cannot be destroyed
Therefore…energy can only be transformed into other types of
energy.
In photosynthesis:Electromagnetic energy (sun) Chemical Energy (sugar)
In respiration:Chemical energy (sugar) Different type of Chem. Energy (ATP)
