Get out ISN we are taking Notes On Photosynthesis Pick up homework Due Monday Quiz Friday!! Content Obj. Students will be able to demonstrate comprehension of Photosynthesis by writing down the equations and labeling the reactant and products. Language Obj. Students will read about the process of photosynthesis and write what a plant needs in order to photosynthesize
Cooking Up Some Photosynthesis Fun! Think about this: What is the gas that this boy is breathing out?
What is Photosynthesis? The process of photosynthesis is a chemical reaction. It is the most important chemical reaction on our planet.
What happens during photosynthesis? Plants capture light energy and use that energy to make glucose Sunlight provides the energy needed by chlorophyll to change molecules of carbon dioxide and water into glucose Oxygen is also released in this reaction
Let’s Get Cooking! Ingredients: Corn Muffin Mix Egg Milk Product: Corn Muffins What do I need to turn the ingredients into the product? HEAT from an oven! Muffin Mix + Egg + Milk HEAT Corn Muffins Ingredients (Reactants) Product
How is photosynthesis like making corn muffins? Carbon Dioxide + WaterGlucose + Oxygen Muffin Mix + Egg + Milk HEAT Corn Muffins Ingredients (Reactants) Product ReactantsProducts Photosynthesis Reactants? Photosynthesis Products? What is needed to change reactants to products? LIGHT!
Photosynthesis 6CO 2 + 6H 2 O C 6 H 12 O 6 + 6O 2 Light Carbon Dioxide + Water In the presence of light produces… Glucose + Oxygen Reactants Products

During photosynthesis how do plants take in water (H 2 O)? Through the roots How do plants take in carbon dioxide (CO 2 )? Through openings on the underside of the leaves called stomata.
Click here to see how carbon dioxide enters the plant through the leaves!
Name the two reactants in photosynthesis: 1. Carbon Dioxide 2. Water
What are the structures in the leaf where carbon dioxide enters the plant? Stomata
6CO 2 + 6H 2 O C 6 H 12 O 6 + 6O 2 Light Carbon Dioxide + Water In the presence of light produces… Glucose + Oxygen Let’s look at the products of photosynthesis! ReactantsProducts
Products of Photosynthesis During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O 2 ) and a form of sugar called glucose (C 6 H 12 O 6 ).

What 2 things do the plants do with the glucose that is produced during photosynthesis? 1. Use it as energy for life processes. 2. Store extra for later use.
The oxygen is a byproduct that is not needed by the plant. The oxygen will leave the plant through the stomata and enter Earth’s atmosphere. What happens to the oxygen produced during photosynthesis?
What are the products of photosynthesis? 1. Glucose 2. Oxygen
How does the byproduct oxygen leave the plant? Through the stomata!
Putting It All Together With Light
Let’s Wrap Everything Up!
What three things are needed by plants in order for photosynthesis to occur?
What are the reactants of photosynthesis?
Carbon Dioxide (CO 2 ) Water (H 2 O)
What are the products of photosynthesis?
What else, besides carbon dioxide and water, must plants have in order to perform photosynthesis? Hint: In our experiment, it affected the rate of photosynthesis!
