Plant roots
Endodermis
Controls absorption of water and nutrients
Region of elongation
new cells begin to increase in length
Region of maturation
cells mature into various tissues
Epidermis
Root hairs maximize water absorption

Responsible for extension of roots and shoots
Cortex
Transports substances between vascular and epidermis
Root cap
Reduces friction and protects root when growing
