Think About It Essential Question Many people claim they talk to their houseplants. They do this because they think it helps their plants grow and remain healthy. What do you think? Explain your answer.

What are we learning today? Benchmarks: §SC. 912. L. 14. 7* §SC. 912. L. 18. 7 -Identify the reactants, products, and basic functions of photosynthesis. Objectives: • I will state the overall equation of photosynthesis. • I will describe the factors that affect photosynthesis.

What Is Photosynthesis? q. Comes from the Greek words: qphoto - light qsynthesis - putting together Therefore, it means “using light to put something together” During photosynthesis, plants use the energy from sunlight to convert water and carbon dioxide into carbohydrates and oxygen. The energy is now STORED in the carbohydrate (STARCH) molecule.

What is Photosynthesis? • Photosynthesis is the conversion of Solar Energy (Light Energy) into

What is Photosynthesis? • Photosynthesis is the conversion of Solar Energy (Light Energy) into a chemical energy • Photosynthesis is the process in which plants are able to make their own food.

Chemical Formula Reactants Products • Photosynthesis: 6 CO 2 + 6 H 2 O

Chemical Formula Reactants Products • Photosynthesis: 6 CO 2 + 6 H 2 O + Light → C 6 H 12 O 6 + 6 O 2 • What are the reactants and products of Photosynthesis? (Carbon Dioxide) + (Water) + Light-------> (Sugar-Glucose)+ (Oxygen) • Cellular Respiration: C 6 HWhat + 6 O 6 CO 2 +and 6 Hproducts the reactants 12 O 6 are 2 → 2 O + ATP of Cellular Respiration?

WHAT’S HAPPENING? Solar energy (Light Energy) This is Chemical Energy (Glucose- Sugar) Photosynthesis

Where does Photosynthesis Occur? • Photosynthesis occurs in the chloroplast of each cell of

Where does Photosynthesis Occur? • Photosynthesis occurs in the chloroplast of each cell of photosynthetic autotrophs. Three kingdoms: • 1. Which Kingdoms would you Protists (Algae) expect to find these type of 2. Plants organisms? 3. Some Bacteria

Chloroplast Function of chloroplast: Carries out photosynthesis Chloroplasts contain a magic compound, chlorophyll, that

Chloroplast Function of chloroplast: Carries out photosynthesis Chloroplasts contain a magic compound, chlorophyll, that can absorb sunlight and start the whole process

Light is not needed for the ENTIRE process of photosynthesis. There are two parts of photosynthesis Light Dependent Reactions Light Independent Reactions • Light is NOT NEEDED • Light energy • ATP energy is absorbed by used to make chlorophyll sugar and turned (GLUCOSE) into ATP

Think About This: How would leaf size affect the process of photosynthesis? What could

Think About This: How would leaf size affect the process of photosynthesis? What could possibly happen if there was limited CO 2 absorbed by a plant?
