Functions of Leaves
Plant Parts
• Leaves– Provide food
(photosynthesis)– Have chloroplasts
(green coloring-chlorophyll)
– Transpiration (“sweating”)
– Respiration
Photosynthesis
• Leaves collect sunlight, water and carbon dioxide to make sugar (food) for the plant– This food is then
transported through the phloem
• The chemical equation for this process is
6 H2O + 6 CO2 C6H12O6 + 6 O2

Respiration
• Leaves break down sugars to get energy
• This process releases excess water as waste
• The chemical equation is
• C6H12O6 + 6 O2 energy + 6 H2O + 6 CO2
