Photosynthesis

What is Photosynthesis? The process by which some organisms use sunlight, carbon dioxide, and water to produce sugar and oxygen. It is the respiration of plants Organisms that use photosynthesis are called producers. They make and consume their own food

What is the equation for photosynthesis What is the equation for photosynthesis? 6CO2 + 6H2O sunlight C6H12O6 + 6O2 What is this stuff? 6 CO2 = Six C6H12O6 = One 6 H2O = Six 6O2 = Six GLUCOSE (Sugar) MOLECULE CARBON DIOXIDE MOLECULES OXYGEN MOLECULES WATER MOLECULES

Plant vs. Animal Respiration Plant Respiration formula: 6CO2 + 6H2O sunlight C6H12O6 + 6O2 Animal Respiration formula: C6H12O6 + 6O2 6H2O + 6CO2 Animals breathe in Oxygen and Eat Sugar produced by the plants and Plants “breathe” in Carbon dioxide produced by the Animals. Knowing this, could animals survive with out plants and could plants live without animals?

Leaves and Photosynthesis Photosynthesis occurs in the leaf structure of green plants Water comes in from the roots of the plant and travels up a tube called xylem Carbon Dioxide enters the plant through holes in the leaves called stoma The sunlight activates special sugar producing cells called chloroplasts The sugar enters tubes called phloem to travel to other parts of the plant The oxygen exits out of the stoma

Each structure on a leaf serves a different function? Stomata – opening that allows CO2 in and O2 out Guard Cells – surround stoma and control the opening and closing of the stoma (plural of “Stomata”) Phloem – tube that transports nutrients throughout plant (glucose) Xylem – tube that transports water throughout plant Cuticle – waxy layer that coats the surface of plants; keeps in moisture Chloroplasts – structure that contains chlorophyll – this is where the glucose is made & where photosynthesis takes place
