• The Sun supplies light and heat energy. • Types:
Unit 1: o Aerobic: Needs oxygen (O2) occurs in people, plants,
animals; releases more energy.
Photosynthesis o Anaerobic: Does not need oxygen; produces lactic

1.2 Photosynthesis
• Definition: Process where green plants produce food
(glucose) and oxygen (O2).
• Requirements:

o Water (H2O)
o Chlorophyll (green pigment)
• Chlorophyll converts light energy to chemical energy. Photosynthesis Respiration
• Products: Action Food is produced. Food is broken down
o Glucose (C6H12O6) Energy Energy is stored. Energy is released.
o Oxygen (O2) Location Only in cells with chlorophyll. Takes place in all living cells.
• Chemical Reaction: Light needed Needs sunlight. Does not need light.
o CO2 + H2O (+ light/chlorophyll) → glucose + O2. Metabolic Anabolic (constructive). Catabolic (destructive).
• Metabolic Type: Anabolic (constructive; energy is
stored).
• Plants are autotrophs (producers).
• CO2 absorbed and O2 released via stomata (gaseous
exchange).
• Excess food is stored as starch.
