Root Systems and Types of Roots Quiz

Study Notes

Root Systems: Types Based on Origin

Taproot System: Develops from the primary root, which grows vertically downward.
Fibrous Root System: Arises from numerous adventitious roots that originate from the stem or lower nodes.
Adventitious Roots: Roots that develop from any part of the plant other than the radicle.

Root System Structures

Primary root: The first root that emerges from the seed. It is crucial for developing the taproot system.
Secondary root: Branches that arise from the primary root, forming a taproot system.

Regions of the Root Tip

Root Cap: Protects the delicate apical meristem as it pushes through the soil. Composed of living cells that are continually sloughed off.
Apical Meristem: Undifferentiated cells located at the tip of the root. Responsible for increasing the length of the root.
Zone of Elongation: A region just behind the apical meristem where cells are elongated and increased in size.
Zone of Maturation: Region where cells differentiate into specialized cells, forming tissues like the vascular tissues (xylem and phloem).
Root Hair Zone: An area where root hairs, tiny projections that increase the surface area for water and nutrient absorption, develop.
