1. Cellular Respiration and Photosynthesis
Outline 3.6

2. In plants and other autotrophs, both processes may occur within individual cells
This is possible because plants contain both chloroplasts and mitochondria
Photosynthesis uses the products of cellular respiration (CO2) and cellular respiration uses the products of photosynthesis (O2)
