Photosynthesis Photosynthesis is the synthesis of glucose from CO 2 and water in the presence of sunlight and chlorophyll, with oxygen as a by product. Autotrophic process Stored as carbohydrate in their bodies.

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!

Plants use sunlight to turn water and carbon dioxide into glucose. 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. Photo-synthesis means "putting together with light."

Photosynthesis Carbon dioxide + water glucose + oxygen sunlight absorbed by chlorophyll 6 CO 2 + 6 H 2 O + energy C 6 H 12 O 6 + 6 O 2 As can be seen from the equation for photosynthesis, the wood, bark, and root came from water and carbon dioxide .

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