Jobs of Roots
Absorb water and minerals from the ground
Hold pant in placeStore food for the plant

ROOT SYSTEMS
Jobs of Stems
Hold up other structures (leaves, flowers)Carry food from roots to leaves
Take food back down for storage
Xylem Phloem

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

SEPTALS PETALS
Leaf-like partsLocated at the base
of the flower
Colorful parts of the flower
Arranged within the sepals
STAMENSMale part of the flower
Located within the petals
CARPELSFemale part of flower
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
