Zone of Elongation
Tissues are all Quite Permeable
Zone of Maturation/ Root Hair System
Root Hairs Grow Outward, Increasing Water Absorption
External Structure of Roots
Structure of Individual Roots
Root Cap
Thick Layer of Cells that Surrounds the Apical Meristem

Just Behind the Root Cap and Apical Meristem
Root Hair Zone
Region in Which Many Epidermal Cells Extend as Narrow Trichomes
Organization of Root Systems
Lateral Roots or Branch Roots
Smaller Roots That Stem From the Prominent Taproot
Radicle
The Embryonic Root
Fibrous Root System
Arises Because the Radicle Dies due to Germination

Roots Provide Long Term Storage for Carbohydrates
Prop Roots
Do Not Make Contact With the Soil, They Transport Nutrients and Water to Stem
