Photosynthesis Notes

Describe Photosynthesis The process of changing light energy to chemical energy which is stored as sugar Occurs in plants and some algae Plants need sunlight, Carbon Dioxide (CO2 ), and Water (H2O) as REACTANTS Describe Photosynthesis

Occurs in the ____________of plants ___________is the green pigment inside chloroplasts that absorb sunlight chloroplasts Chlorophyll

As the chlorophyll in leaves decays in the autumn, the green color fades and is replaced by the oranges and reds of carotenoids.

(What is needed or Taken in) (What is created/produced) H2O Water Reactants CO2 Carbon Dioxide Light NADP+ ADP + P ATP NADPH (What is created/produced) Chloroplast C6H12O6 Glucose O2 Oxygen Products

Photosynthesis: Photosynthesis is the process by which the energy of sunlight is converted into the energy of glucose. carbon dioxide  +  water  +  light                         glucose  +  oxygen 6CO2 + 6H2O + light C6H12O6 + 6O2

Photosynthesis: Photosynthesis is the process by which the energy of sunlight is converted into the energy of glucose. carbon dioxide + water + light glucose + oxygen REACTANTS PRODUCTS

Photosynthesis: Photosynthesis is the process by which the energy of _________ is ________ into the energy of __________ carbon dioxide + water + light glucose + oxygen ______________ ______________

What happens during photosynthesis? Sunlight provides the energy needed to change carbon dioxide and water into glucose Oxygen is released as a waste What happens during photosynthesis?

What happens during photosynthesis? Carbon dioxide enters the leaf through holes called stomata CO2 combines with the stored energy in the chloroplasts through a chemical reaction to make glucose The sugar is moved through tubes in the leaf to the roots, stems and fruits of the plants Some of the sugar is used right away by the plant for energy; some is stored as starch; and some is built into plant tissue

Why is this important to us? Without photosynthesis, plants wouldn’t exist. We cannot make our own food (glucose, energy), we must get our food from plants. The oxygen released is necessary for ALL living things. Remember: Producers/Plants are the base of the food chain! Why is this important to us?

Water, Sunlight, Carbon Dioxide How do we build an equation for photosynthesis? What do plants (chloroplasts in the cells) need? What do plants create? Which side of the equation are the reactants? Which side of the equation are the products? Equation/ Formula: Water, Sunlight, Carbon Dioxide Glucose, Oxygen Left of the arrow Right of the arrow

Photosynthesis Write an equation for photosynthesis ____ + ____ + ____ ____ + ____ Photosynthesis Water + Carbon Dioxide + sunlight Glucose + Oxygen REACTANTS PRODUCTS Now label which side are the PRODUCTS & REACTANTS!
