Photosynthesis Objective 2: The student will demonstrate an understanding of living systems and the environment. (7.8) Science concepts. The student knows that complex interactions occur between matter and energy. The student is expected to: (B) identify that radiant energy from the Sun is transferred into chemical energy through the process of photosynthesis.

Photosynthesis Photosynthesis changes light energy into food (chemical) energy. s/renewable/images/photosynthesis1.gif

Photosynthesis Begins with (reactants): –Sunlight (radiant energy) –Water (from the ground) –Carbon dioxide (from the air)

Photosynthesis Ends with (products): –Oxygen –Glucose Stored chemical energy

Photosynthesis

Reactants Products CO 2 + H 2 O + light  C 6 H 12 O 6 + O 2 From the air Water taken up by roots Energy (sunlight) Glucose Energy Fuel Oxygen
