Photosynthesis & RespirationI). Photosynthesis and Respiration A). Photosynthesis
1). Is a chemical reaction that uses energy from the sun, carbon dioxide from the atmosphere and water to create sugars for energy for themselves and animals that eat the sugars and oxygen.
2). Chemical Reaction for Photosynthesis:
6CO2 + 6H2O Light
C6H12O6 + 6O2
Carbon Dioxide water Sugars
Oxygen
C). Photosynthesis occurs in the chloroplasts of plants.
1). Chloroplasts have two important structures:
a). Thylakoids: Photosynthetic sacs that make up the membrane that surrounds the chloroplast.
b). Stroma: The fliud portion of the chloroplast outside of the thylakoids.
B). Respiration1). Is a chemical reaction that uses sugars created by plants during photosynthesis, and oxygen to release energy, water and carbon dioxide.2). Chemical Reaction for Respiration:6O2 + C6H12O6 6CO2 + 6H2O + Energy
Oxygen Glucose (Sugar) Carbon Dioxide Water
II). The Relationship between Photosynthesisand Respiration.A). Photosynthesis and respiration are basically the opposte of each other.B). Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere and cellular respiration uses that oxygen to release enrgy from food.
