Photosynthesis

Photosynthesis Vocabulary Photosynthesis- A process by which plants convert sunlight, water, and carbon dioxide into food energy (sugar), oxygen and water. Chloroplast- An elongated cell organelle containing chlorophyll where photosynthesis takes place. Chlorophyll- A green molecule which uses light energy from sunlight to change water and carbon dioxide gas into sugar and oxygen

Photosynthesis Equation H2O + CO2 + light  O2 + C6H12O6 Water+ Carbon + sun  Oxygen + glucose Dioxide (sugar)

The chlorophyll absorbs the sunlight. Chlorophyll is the green pigment inside the chloroplasts of plant cells that makes leaves green!

Chlorophyll then uses sunlight to change water, carbon dioxide and, nutrients from the soil. CO2

The chlorophyll processes the ingredients to make sugar (plant food) and oxygen. Sugar + O2

Animals make the CO2 plants need Plants make the O2 animals need But, what about animals ? Animals make the CO2 plants need Plants make the O2 animals need
