What is a lateral root in biology?

What is a lateral root in biology?

Lateral roots are smaller roots that extend horizontally from the primary tap root and help to anchor the plant securely into the soil.

What is the function of the lateral root?

They contribute to anchoring the plant securely into the soil, increasing water uptake, and facilitates the extraction of nutrients required for the growth and development of the plant. Lateral roots increase the surface area of a plant's root system and can be found in great abundance in several plant species.

What is lateral root short answer?

Lateral roots are the smaller roots that emerge horizontally from the taproot or the main root. They are said to have an endogenous origin since they are produced from called pericycle. The pericycle is a thin layer of cells that is located between the vascular bundles and endodermis.

What are lateral roots called?

…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).

Where do lateral roots form from?

Lateral roots originate from a subset of pericycle cells situated in front of the xylem poles (Dolan et al., 1993). Since the pericycle is located deep within the root, new primordia have to break through the three overlying outer layers of cells (Fig. 2B.).Jul 27, 2009

What is lateral or secondary root?

There are generally two types of root systems present, taproot system, and adventitious root system. The taproot develops from the radicle of an embryo and forms primary root which later gives rise to secondary roots which are also known as lateral roots which further form tertiary roots and rootlets.

What are secondary lateral roots?

Secondary, or lateral, meristems, which are found in all woody plants and in some herbaceous ones, consist of the vascular cambium and the cork cambium. They produce secondary tissues from a ring of vascular cambium in stems and roots.

What are secondary roots?

What are the primary and secondary roots? Primary roots are the early roots in young plants that consist of taproots, basal roots, and lateral roots. Secondary roots are the side branches of the primary roots.

What are second roots?

A secondary root or lateral root is a side branch of the main root, a root or a fine rootlet that derives from the primary root. Secondary roots is also used to describe an adventitious root that develops on a stem or leaves.

Where do lateral secondary roots arise?

Lateral roots or secondary roots originate from a tissue layer called as the pericycle. The pericycle is located between the stele and the endodermis.

What is the function of the secondary root?

Secondary functions are performed by certain roots, which are specifically modified for the purpose only in some plants, such functions include; storage food, provision of additional support, absorption of atmospheric moisture, assimilation/photosynthesis, sucking food from host, reproduction, respiration, better ...
