Exploring Photosynthesis and Cell Respiration

The video tutorial explains how living organisms obtain energy through photosynthesis and cellular respiration. It introduces the concepts of heterotrophs and autotrophs, detailing how plants produce food via photosynthesis in chloroplasts using sunlight, water, and carbon dioxide. The process results in glucose and oxygen, which are used in cellular respiration to release energy in the form of ATP. The tutorial highlights the interdependence of these processes, emphasizing their importance in maintaining life and atmospheric balance.

What type of organisms produce their own food?

What is the equation for photosynthesis?

• C6H12O6 + 6O2 -> 6CO2 + 6H2O + Energy

• 6CO2 + 6H2O + Light Energy -> C6H12O6 + 6O2

• 6H2O + 6CO2 -> C6H12O6 + 6O2

• 6O2 + C6H12O6 -> 6CO2 + 6H2O
