The process of root formation begins with seed germination.
After emerging from the seed, the radicle of the plant embryo creates the root system.
The root cap shields the tip of the root, which is unique to roots and unlike any other plant structure.
A cell division zone, an elongation zone, and a maturation zone are divided into three zones on the root tip.
Roots become larger as meristematic cells divide.
As undifferentiated (or barely differentiated) cells, they are the source of many of the cells that go on to rapidly differentiate/specialize and generate distinct portions of the plant.
As a result of the meristem cells, root cells expand in size.
