Question

why lateral roots are endogenous ?

Answer 1

The taproot are produced smaller lateral roots (secondary roots) that grow horizontally or diagonally. These secondary roots further produce their own smaller lateral roots (tertiary roots). Thus, many orders of roots of descending size are produced from a single prominent root, the taproot. Most dicotyledons produce taproots.

Because lateral roots are initiated in the pericycle and grow out through the cortex and epidermis, they are said to have an internal, or endogenous, origin, in contrast to the external, or exogenous, origin of leaves and the apical meristem of stems..............

Answer 2

Plant Anatomy

Explanation:

• Origin of Lateral Roots The parallel roots are endogenous in origin (from a more profound layer)
• The seat of its origin is cells of pericycle, for the most part opposite a protoxylem group, become meristematic and continue partitioning periclinally and anticlinally
• Lateral roots are produced in a definite pattern
• This branching of roots likewise adds to water uptake, and facilitates the extraction of supplements required for the development and improvement of the plant
