Root Tip and Mitosis
Use a root tip to connect plant growth zones with the cell division stages visible near the meristem.

Root cap
Protective tip that helps the root push through soil.
Root tips are useful for seeing mitosis because the meristematic zone contains many actively dividing cells. Behind it, cells elongate and then differentiate into specialized tissues.
The root cap protects the growing tip, while root hairs farther back increase surface area for uptake.
Key Idea
Plant growth is spatially organized: division, elongation, and differentiation happen in different zones along the root.
