Photosynthesis Cellular Respiration

Respiration �Process by which humans breathe in Oxygen (O 2) and give out Carbon Dioxide (CO 2)

The Atmosphere �Is made up of 78 % Nitrogen and 20 % Oxygen �If we use up ALL the oxygen who produces more Oxygen? �Trees – By the process of photosynthesis �Plants make our oxygen

Photosynthesis �Process by which plants convert light energy to chemical energy (ATP) �This takes place in the chloroplasts which contain chlorophyll (green in color) �Ingredients: light, Carbon Dioxide (CO 2) and water (H 2 O) for this process �Products: give out Oxygen (O 2) and sugar (C 6 H 12 O 6)

Photosynthesis Equation 6 CO 2 + 6 __ __ H 2 O sunlight C 6 H 12 O 6 +6__ O 2 Balance the equation (R. H. S = L. H. S) Why do we need plants so much? Because plants create nutrients from inorganic materials. Plants take in CO 2 and give out O 2

Cellular Respiration �The reverse of Photosynthesis �Happens in animal cells in the mitochondria �What do we breathe in? �Oxygen (O 2) �What do we give out? �Carbon Dioxide (CO 2) and water vapor (H 2 O) �The process of breathing in Oxygen and giving out Carbon Dioxide and water vapor is called Cellular Respiration
