Get out Spiral - Warm Up: Being as detailed as you can, explain (in words your own words) what is happening in the diagram below 2006-2007

Rate yourself based on what you know about Photosynthesis Scale 0-4 Rate yourself based on what you know about Photosynthesis 4 I can name organelles and structures used in photosynthesis, identify/name elements used in photosynthesis, write the equation for photosynthesis, and relate the equation to cellular respiration. 3 I can name the organelles and structures used in photosynthesis, identify and name the elements going in to photosynthesis, and write the equation for photosynthesis 2 I can identify some organelles and recognize the photosynthesis equation 1 I cannot explain or identify elements, organelles, structures, or the equation for photosynthesis 2006-2007

Photosynthesis: Life from Light and Air Remember to Title Number & Update Table of Contents Photosynthesis: Life from Light and Air

All LIVING organisms need energy! Organisms get energy either directly or indirectly from energy through sunlight in a process called photosynthesis In your table (Groups of 2-3) come up with a definition for Photosynthesis

Organisms that photosynthesis are called Autotrophs Photosynthesis: a process by which a cell captures energy in sunlight and uses it to make sugar (food). Organisms that photosynthesis are called Autotrophs Organisms that obtain energy by consuming autotrophs are called Heterotrophs 2006-2007

Draw a quick version of a plant in your spiral Product Sugar (energy) Reactant Product Reactant The organelle responsible for photosynthesis is the Chloroplast Reactant

So what does a plant need? Bring In light CO2 H2O Let Out O2 Move Around Sugars (energy) leaves shoot roots Brainstorm what the Chemical equation is  + 6CO2 6H2O C6H12O6 6O2 light energy  +

Stomates & Guard Cells guard cell stomate Function of stomates CO2 in O2 out H2O out Function of guard cells– to open and close the stomata (hole) LOCATED ON BOTTOM OF LEAVES! open & close stomates guard cell stomate

Guard cells & Homeostasis keeping the internal environment of the plant balanced Stomates open let CO2 in let H2O out let O2 out Stomates close if too much H2O is evaporating

Get out Spiral – go back and re write or correct your warm up by explaining the photo below. 2006-2007

On the left hand side of your notebook complete the leaf diagram by correctly placing the arrows products and reactant in photosynthesis equation

How do plants make energy & food? Plants use the energy from the sun to make ATP energy to make sugars glucose, sucrose, cellulose, starch, & more sun ATP sugars

Using light & air to grow plants Photosynthesis using sun’s energy to make ATP using CO2 & water to make sugar HAPPENS in chloroplasts (ATP) = used to build the sugar  glucose + oxygen carbon dioxide sun energy + water + 6CO2 6H2O C6H12O6 6O2 sun energy  +

What do plants need to grow? The “factory” for making energy & sugars chloroplast Fuels sunlight carbon dioxide water The Helpers enzymes Make ATP! Make sugar! I can do it all… sun CO2 ATP enzymes sugars H2O

Chloroplasts are only in plants animal cells plant cells

glucose + oxygen  carbon + water + energy How are they connected? Respiration glucose + oxygen  carbon + water + energy dioxide C6H12O6 6O2 6CO2 6H2O ATP  + Photosynthesis So, in effect, photosynthesis is respiration run backwards powered by light. Cellular Respiration oxidize C6H12O6  CO2 & produce H2O fall of electrons downhill to O2 exergonic Photosynthesis reduce CO2  C6H12O6 & produce O2 boost electrons uphill by splitting H2O endergonic 6CO2 6H2O C6H12O6 6O2 light energy  +  glucose + oxygen carbon dioxide sun + water +

The Great Circle of Life! sun Energy cycle Photosynthesis plants H2O CO2 glucose sugars O2 animals, plants Cellular Respiration ATP The Great Circle of Life! Mufasa?

The poetic perspective All of the solid material of every plant was built out of thin air All of the solid material of every animal was built from plant material sun air Then all the cats, dogs, mice, people & elephants… are really strands of air woven together by sunlight!
