Lateral Roots

Lateral Root showing the Vascular Connection between it and the parent Stele.	Lateral Roots showing their Connection to the Vascular Cylinder in their parent root. This is from an aquatic plant and has Aerenchyma as its Cortex.
Tap root system of Zamia (my favoritePlant)	Lateral roots are produced in a definite pattern. The youngest roots are close (proximal) to the apex. The pattern of lateral root production is readily observed with tap root systems. The tap root can also be called the primary root while its branches are called secondary or lateral roots.
Plant with a Fibrous Root System. These have more than one dominant root.	The origin of lateral roots can be unraveled for species that have fibrous root systems. A clear pattern emerges with careful study.
	Note the lateral roots which have emerged from an aerial root of a plam. Careful study will reveal the patern of root production. Why do you think they are so stubby?
	*Locate the lateral roots in this picture of ie ie* roots. What is their principal function in this case?**
