1. Photosynthesis
● Process by which organisms use energy from sunlight to make their own food (glucose)
● Glucose is a simple sugar
● Photosynthesis occurs in the chloroplasts of plant cells and some bacteria
● Chloroplasts have a green pigment called chlorophyll
● Steps of photosynthesis
o 1. Light reaction: chlorophyll in the chloroplasts absorbs sunlight
o 2. Dark reaction: The energy from the sunlight is used to make glucose
● Light energy is completely changed into chemical energy (glucose)
● Chemical equation for photosynthesis
● 6CO2+ 6H2O + light energy → C6H12O6+ O2
