The Meristematic Region or Growing Point
This region occurs immediately behind the root cap. The Meristematic region consists of meristematic tissue and is protected by the root cap. The cells are very activeand divide rapidly to form new cells which differentiate later to form more specialized root tissues. The cells of this region also replace the cells rubbed-off from the root cap and provide additional cells for the next region.
Function
- This is the region where the cells divide and where additional cells are provided for the zone of elongation.
The Region of Elongation
The cells formed in the meristematic region undergo rapid growth in length. This causes the root to elongate and penetrate deeper into the soil in search for water and mineral salts. The meristematic and elongation zones are also referred to as the region of growth.
Function
- In this region the cells undergo rapid enlargement,i.e. the cells undergo rapid growth in length.
The Root-hair Region
The root hair region occurs a short distance above the region of elongation. Here a large number of fine, hair-like outgrowths are formed. The root hairs arise from the epidermal tissue of the root and are called root hairs. The root hairs are short and short-lived and develop on theprimary and secondary roots. A root-hair consists of the following parts: a thin cell wall, a thin lining of cytoplasm which contains thenucleus and a comparatively large vacuole containing cell sap.
Function
- The main function of the root hairs is to increase the area of absorption of the root.
The Mature Region
The mature region is situated above the root hair region. Here the root becomes thicker and secondary or lateral rootsare developed. The secondary roots in turn rebranch to form tertiary roots. Each lateral branch has its own cap, root hairs, meristematic, elongation and mature regions. The roots in this region are covered by a protective cork layer .
Functions
- In this region the cells undergo differentiation into specialized cells,(e.g. xylem and phloem).
- It also serves to anchor the plant.

Why is region of meristmatic activity is important in roots?
Meristems bring about the growth or buds and production of a plant, from its beginnings as a root.

Apical meristem is the term used to describe the region of plant tissue found at the tips of stems and roots that is responsible for their primary growth in length.
Where does the last name Bazaldua originally from?
The last name Bazaldua is of Spanish origin and is believed to have roots in the Basque region of Spain. It may have originated from a place name or a topographical feature in that region.
Why is cambium layer scraped of in marcotting?
Marcotting- the target region is wounded and then surrounded in a moisture-retaining wrapper such as sphagnum moss, which is further surrounded in a moisture barrier such as polyethylene film. Rooting hormone is often applied to encourage the wounded region to grow roots. When sufficient roots have grown from the wound, the stem from the parent plant is removed and planted.
Where is the vascular region?
The vascular region typically refers to an area in plants where the vascular tissue responsible for transporting water and nutrients is located. In plants, this region is found within the stem and roots, arranged in a network to facilitate the movement of fluids throughout the plant.
Where region in the Philippines is the proverb from?
The proverb "Ang hindi marunong lumingon sa pinanggalingan ay hindi makararating sa paroroonan" is commonly attributed to the Tagalog region in the Philippines. This saying emphasizes the importance of remembering one's roots to move forward in life.
What region of soil profile reacts the most?
The topsoil region of a soil profile typically reacts the most due to its higher concentration of organic matter and biological activity. This region is where most nutrient cycling and plant roots are active, leading to greater reactivity compared to subsoil layers.
What kind of roots does roots have?
Roots don't have roots, plants have roots.
