Dicot and Monocot Root
Dicots and monocots, two major groups of flowering plants, exhibit differences in their root structures:
-
Dicot Root:
- Typically features a taproot system with a primary root that grows deep into the soil.
- Secondary growth is common, leading to an increase in girth.
- Vascular cambium forms between the xylem and phloem, contributing to secondary growth.
- Xylem often forms a star-shaped pattern in cross-section.
-
Monocot Root:
- Usually has a fibrous root system with numerous roots spreading out horizontally.
- Lacks secondary growth, as vascular cambium is absent.
- Vascular bundles are arranged in a ring pattern in the cross-section, each bundle being closed (i.e., without cambium).
