Cell Processes The CELL must undergo certain processes in order to ensure the survival of the organism as a whole.

Photosynthesis Plants use light energy (sunlight) to combine carbon dioxide (CO 2 ) and water (H 2 O) to make simple sugars (C 6 H 12 O 6 ) Plants use light energy (sunlight) to combine carbon dioxide (CO 2 ) and water (H 2 O) to make simple sugars (C 6 H 12 O 6 )

Why is this important to us? We cannot make our own food (glucose or energy) we must get our food from plants. We cannot make our own food (glucose or energy) we must get our food from plants. Plants are the first step in the food chain. Plants are the first step in the food chain.

What is all this “food” (better known as glucose) used for? It can be used by the plant to make energy in the mitochondria It can be used by the plant to make energy in the mitochondria It can be stored by the plants in vacuoles It can be stored by the plants in vacuoles It can be eaten by a consumer It can be eaten by a consumer Little Girl and her Plant (Ms Dunn says read it carefully….)

What happens during photosynthesis? Chloroplasts in plant cells capture light energy and use that energy to make glucose or “food” Chloroplasts in plant cells capture light energy and use that energy to make glucose or “food” Oxygen gas is also released as a by-product in this reaction Oxygen gas is also released as a by-product in this reaction

Photosynthesis

Cellular Respiration ALL organisms break down simple sugars (C 6 H 12 O 6 ) for the energy they contain ALL organisms break down simple sugars (C 6 H 12 O 6 ) for the energy they contain

Cellular Respiration Sugar is broken down into Carbon Dioxide (CO 2 ) and Water (H 2 O) Sugar is broken down into Carbon Dioxide (CO 2 ) and Water (H 2 O) The Chemical Formula looks like this: The Chemical Formula looks like this: C6H12O6 + O2  CO2 + H2O + ENERGY Sugar + Oxygen  Carbon Dioxide + water + ENERGY Or in English…….

What’s this energy for? To build new cell parts To build new cell parts To repair cell parts To repair cell parts To reproduce cells To reproduce cells

Where does it happen? Cellular Respiration occurs in the mitochondria!!! Cellular Respiration occurs in the mitochondria!!!
