2 PhotosynthesisThe process by which energy from the sun is used to convert carbon dioxide and water into glucose and oxygen
3 Photosynthesis Con’tPhotosynthesis occurs in algae, certain types of prokaryotes, and the chloroplasts of eukaryotic plantsStructure and shape of a leaf is adapted for photosynthesisLeaves are flat, only a few cells thick, and expose a large surface area to the sunCO2 from air enters leaf via adjustable pores, stomata, in epidermis
4 Chemical Equation of Photosynthesis 6CO2 + 6H2O + Energy C6H12O6 + 6O2(Light)
5 Cellular RespirationThe process by which the stored energy in glucose molecules is broken down to release ATP.
6 Chemical Equation of Cellular Respiration C6H12O6 + 6O2 6CO2 + 6H2O + Energy(ATP)
7 Cellular Respiration Con’t Cellular respiration occurs in all eukaryotic organismsBegins in the cytoplasm, but is completed in the mitochondriaProduces ATP for the cellRemember ATP is the only usable form of energy for the cell
8 Cellular Respiration is NOT: BreathingExchange of gases with the atmosphereThe transport of oxygen and carbon dioxide to/from the cell.
9 Types of Cellular respiration AerobicRequires oxygen in order to take placeThis process produces more energyAnaerobicDoes not require oxygen to take placeSimple process that produces energy quickly
