PHOTOSYNTHESIS Autotrophic Process: Plants and plant-like organisms make their energy (glucose) from sunlight. Stored as carbohydrate in their bodies. 6CO2 + 6H2O + sunlight  C6H12O6 + 6O2

Why is Photosynthesis important? Makes organic molecules (glucose) out of inorganic materials (carbon dioxide and water). It begins all food chains/webs. Thus all life is supported by this process. It also makes oxygen gas!!

Photosynthesis-starts to ecological food webs!

Photo-synthesis means "putting together with light." Plants use sunlight (radiant energy) to turn water and carbon dioxide into glucose (chemical energy.) Glucose is a kind of sugar. Plants use glucose as food for energy and as a building block for growing. Autotrophs make glucose and heterotrophs are consumers of it.

Photosynthesis 6CO2 + 6H2O + energy  C6H12O6 + 6O2 Carbon dioxide + water glucose + oxygen sunlight absorbed by chlorophyll 6CO2 + 6H2O + energy  C6H12O6 + 6O2 As can be seen from the equation for photosynthesis, the wood, bark, and root came from water and carbon dioxide.

Plants in Action Check it! What is the process that uses the sun’s energy to make simple sugars?

The photograph below is an elodea leaf X 400 The photograph below is an elodea leaf X 400. Individual cells are clearly visible. The tiny green structures within the cells are chloroplasts which hold the chlorophyll this is where photosynthesis happens.

Chloroplasts make the sugars!

Leaves are green because they contain Plants Leaves are green because they contain the pigment: chlorophyll Leaves have a large surface area to absorb as much light as possible "Thanks for the Glucose!"

Chloroplasts make the oxygen too!

PHOTOSYNTHESIS Why do we see green? Green color from white light reflected NOT absorbed Chloroplast: organelle responsible for photosynthesis Chlorophyll: located within Chloroplast Green pigment

Chlorophyll: A Light Absorbing Pigment The Solar Panel Chemical!

EQUATION FOR PHOTOSYNTHESIS Make sure to write this down completely!!! WATER OXYGEN 6CO2 + 6H2O + ENERGY C6H12O6 + 6O2 CARBON DIOXIDE GLUCOSE
