Photosynthesis & Cellular Respiration

So, how do living organisms get energy?

Photosynthesis

• Cells inside the kelp use energy from the sun to make glucose.

• The kelp stores the glucose in its blades (like leaves).

Cellular Respiration

• Cells in fish use glucose from plants to make ATP or

ENERGY.

Chemical Equation & Label Photosynthesis

6 CO2 + 6 H2O + Sunlight C6H12O6 + 6 O2

Carbon Dioxide + Water + Energy Glucose + Oxygen

Cellular Respiration

C6H12O6 + 6 O2 6 CO2 + 6 H2O + 38 ATPGlucose + Oxygen Carbon dioxide + Water + Energy
