Plant Functions
What do stems & leaves do for a plant???
Stems
Transport of Materials
• Phloem (2)– Carries sugars (food) up
& down in plant
• Xylem (1)– Carries water & mineral
up from roots to all parts of plants
Leaves
Photosynthesis
• Leaves collect sunlight, water and carbon dioxide to make sugar (food) for the plant
• 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
