Next… Plant Physiology

Plants grow and reproduce, as well as, respond to the environment.

Photosynthesis Cellular Respiration CO2 + H2O C6H1206 + O2 CO2 + H2O light Photosynthesis CO2 + H2O C6H1206 + O2 sugar Cellular Respiration CO2 + H2O C6H1206 + O2 sugar energy ADP ATP

Animals grow diffusely

Fig 10.1 Photosynthesis: Plants can make sugar using energy from the sun, water from the ground, and CO2 from the air.
