Roots
Uses for Man
Environment
Roots hold soil together and reduce erosion
Prevent riverbanks from washing away at a faster rate
sustenance
Provides a good source of carbohydrates and fiber
Internal Root structures
Zone of Elongation
Cell enlargement
differentiate into visible patterns
Apical Meristem
Cell division
Quiescent center
Quiescent center cells form new apical meristem if damaged
Zone of Maturation/Root Hair zone
Casparian Strips
Controls minerals that enter xylem water stream
Root hairs grow outward
Cuticle appears
Root cap
Specific structure and growth pattern to protect apical meristem
Mature portion
Absorption of water and maintaining root pressure
External Root Structures
Fibrous
Mass of similarly sized roots
Adventitious roots increase absorption and transportation
Tomatoes
coconut palms
Corn

Types of Roots
Aerial
Live attached to the bark of trees
Contain velamen
Creates waterproof barrier so no water escapes
Prop
Provides stronger support and stability to stay upright
Corn
Palm
Mangroves
Contractile
Contractions occur after root is well secured
bulbs are pulled deeper
Storage

Beets
Mycorrhizae
Relationship with soil fungi
Fungus provides phosphorus to roots
