Where do plants get their mass? September 30- buoyant- ('boi yant)- (adjective)- cheerful; able to float The coach valued him as a member of the team because his buoyant

An acre of pine trees (~120 trees) has the potential to take in roughly 5 tons of CO2 per year.

Autotrophic vs. Heterotrophic Autotrophs are “self-feeders” They can make their own food! Usually they use photosynthesis to make food Heterotrophs are “other feeders” These organisms cannot make their own food They must eat food made by others

Photosynthesis Carbon dioxide + water + light Glucose + oxygen

Where does photosynthesis occur in plants? It occurs in the chloroplasts of plant cells

The structure of a chloroplast Outer membrane Inner membrane Thylakoid membrane Stroma (fluid)

That is photosynthesis in a nutshell. Once sunlight is captured, its energy is trapped in the chemical bonds of sugars such as Glucose That is photosynthesis in a nutshell.

Building plants from sunlight & air Photosynthesis 2 separate processes Light Dependent Reactions collect sun energy use it to make ATP (Energy) Calvin Cycle take the ATP energy collect CO2 from air & H2O from ground use all to build sugars ATP H2O + CO2 sugars carbon dioxide CO2 water H2O sugars C6H12O6 +

A Summary of Photosynthesis Light + H2O + CO2 Light Reactions Calvin Cycle Oxygen + Glucose

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 +
