Botany professor Dr. Joyce Onyenedum explores the development, anatomy, and function of ROOTS–– the hidden heroes behind plant resilience. Roots anchor plants in the soil where they absorb water and nutrients, and their intricate anatomy reflects these essential functions.

Topics covered:

00:00 Root function & evolution
01:06 The root's blueprint: four developmental zones from tip to maturity
2:47 Assembling the protostele
3:24 Expanding the root system through lateral roots
4:05 Extreme root anatomy: mangroves
4:48 Extreme root anatomy: epiphytes
5:15 Extreme root anatomy: cycads
5:40 Recap
