PhotosynthesisPhotosynthesis Plants use light energy (sunlight) to Plants use light energy (sunlight) to

combine carbon dioxide (COcombine carbon dioxide (CO22) and ) and water (Hwater (H22O) to make simple sugars O) to make simple sugars (C(C66HH1212OO66))

Why is this important to Why is this important to us?us?

We cannot make our own food We cannot make our own food (glucose or energy) we must get our (glucose or energy) we must get our food from plants.food from plants.

Plants are the first step in the food Plants are the first step in the food chain.chain.

What is all this “food” What is all this “food” (better known as glucose) (better known as glucose) used for?used for?

It can be used by the plant to make It can be used by the plant to make energy in the mitochondriaenergy in the mitochondria

It can be stored by the plants in It can be stored by the plants in vacuolesvacuoles

It can be eaten by a consumerIt can be eaten by a consumer

Little Girl and her Plant(Ms Dunn says read it carefully….)

What happens during What happens during photosynthesis?photosynthesis?

Chloroplasts in plant cells Chloroplasts in plant cells capture light energy and use capture light energy and use that energy to make glucose that energy to make glucose or “food”or “food”

Oxygen gas is also released Oxygen gas is also released as a by-product in this as a by-product in this reactionreaction

ALL organisms break down ALL organisms break down simple sugars (Csimple sugars (C66HH1212OO66) for ) for the energy they containthe energy they contain

Cellular RespirationCellular Respiration

Sugar is broken down into Sugar is broken down into Carbon Dioxide (COCarbon Dioxide (CO22) and Water ) and Water (H(H22O)O)

The Chemical Formula looks like The Chemical Formula looks like this:this:CC66HH1212OO6 6 ++ OO2 2 COCO2 2 ++ HH22O + ENERGYO + ENERGY

Sugar + Oxygen Carbon Dioxide + water + ENERGY
