ROOT SYSTEMS

Jobs of Stems

Hold up other structures (leaves, flowers)Carry food from roots to leaves

Take food back down for storage

LEAVES

Petiole: connects blade to stemBlade: contains chlorophyll necessary

for making food

Veins:Bring in water for photosynthesisTransport food to all plant parts

• LEAVES CONTAIN SUBSTANCES CALLED PIGMENTS

• P IGMENTS CAUSE LEAVES TO CHANGE COLOR

• THESE LEAVES FALL OFF AND DIE

• NEW LEAVES GROW BACK IN THE SPRING

5 STEPS OF PHOTOSYNTHESIS

1. Water is taken in through roots.2. Water is transported to leaves.3. Carbon dioxide goes into leaves.4. Carbon dioxide spreads to cells that

contain chlorophyll.5. Sunlight turns water in plant into

oxygen.

AFTER PHOTOSYNTHESIS

Hydrogen and Carbon Dioxide make food for the plant

Plant gives off oxygen

Humans and animals use oxygen to breathe
