Epidermis -mineral release from soil → Cortex -
storage → Endodermis - selective
mineral uptake → Pericycle - forms
- branch roots
- periderm → Vascular cylinder
- conduction
- secondary growth → Phloem - conduction of sugar
and amino acid from leaf → Vascular cambium -
divides new xylem + phloem
secondary growth → Xylem - conduction of
water and minerals up from soil
