Do you remember this song?<br />Just give me some light <br />and H20 ohh with CO2<br />then I’ll make glucose <br />and the oxygen <br />you breath in through your nose<br />That’s how photosynthesis flows<br />
Which organisms do this?<br />Organisms known as autotrophs or producers make their own food. <br />They use chloroplasts to create food.<br />Plants are autotrophs<br />
How do autotrophs make their own food?<br />Autotrophic organisms possess cells that contain chlorophyll.<br />Chlorophyll is a green pigment located in the chloroplast and is responsible for giving green plants their color<br />Chlorophyll absorbs light energy from the sun.<br />
What happens next?<br />Autotrophs take carbon dioxide into their cells through diffusion and water into their cells through osmosis.<br />Then a series of reactions that take place that result in the formation of oxygen and glucose<br />
What is glucose used for?<br />When the energy absorbed from the sun is stored in the form of glucose. <br />The glucose is broken down in the mitochondria during cellular respiration then the energy is released in the form of ATP.<br />
What do you notice about these two reactions?<br />C6H12O6 + 6O2 -----> 6CO2 + 6H20 + ATP & <br /> heat<br />6CO2 + 6H20 +light energy -----> C6H12O6<br /> + 6O2<br />The products from photosynthesis are the reactants from cellular respiration and vice versa.<br />
What do the numbers below represent?<br />C6H12O6 + 6O2 -----> 6CO2 + 6H20 + ATP & heat<br />6CO2 + 6H20 + light energy -----> C6H12O6 + 6O2<br />The subscripts let the reader know the amount of each element in a compound.<br />In the compound that is water there are two hydrogen for every oxygen. <br />The large number in the front represents the number molecules of the compound present. There are six water molecules present<br />
