Last time it was shoots, this time it’s roots!
Root Tip – Region where root growth occurs.
Root Apical Meristem – Analogous to the shoot apical meristem (where growth occurs) except more orderly. Located at the tip of the root under the root cap.
Root Cap – A protective layer of cells around the root apical meristem.
Region of Elongation – Area behind root cap and meristem where cells undergo division and expansion.
Region of Maturation – Area where cells continue to differentiate.
Root Hairs – Narrow cells that increase root surface area allowing for greater soil penetration, release of carbon dioxide, and absorption of ions. These live for 4-5 days.
Lateral (Branching) Roots – Smaller roots (often numerous).
