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
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
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 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 .

Roots mainly grow towards regions with higher concentrations of nutrients, water, and oxygen. They also grow away from areas with high levels of toxins or unfavorable soil conditions. Additionally, roots grow towards gravity, a phenomenon known as positive geotropism, with the root tip sensing gravity and growing downwards.
The meristematic regions in plants are the apical meristem (found at the tips of roots and shoots), intercalary meristem (located at the base of leaves or internodes), and lateral meristem (responsible for increasing the girth of stems or roots). These regions are responsible for growth and cell division in plants.
Regions like the Middle East, North Africa, parts of Asia, and some regions in the United States have experienced issues with water scarcity due to factors such as climate change, population growth, and inefficient water management practices.
The difference in fertility rates between the two regions could be attributed to various factors, such as socioeconomic development, access to education and healthcare, cultural norms regarding family size, availability of family planning resources, and government policies promoting or restricting family growth. This can result in variations in birth rates and overall population growth between regions.
The human population is currently experiencing exponential growth, meaning it is increasing at an accelerating rate. This rapid population growth is straining resources and infrastructure in many regions of the world.
Tree roots can damage rocks by growing into cracks and crevices, exerting pressure as they expand. The roots can pry apart the rock, causing it to break or fracture. Over time, repeated growth and expansion of the roots can weaken the rock structure.
Growth in an organism is carefully controlled by regulating the cell cycle. In plants, the roots continue to grow as they search for water and nutrients. These regions of growth are good for studying the cell cycle because at any given time, you can find cells that are undergoing mitosis.

Auxin controls the growth of the plant. Auxin in the roots of the plant inhibits growth whereas in the stems in the stems it encourages growth.
These regions, where cells continuously divide, are where plant growth originates.
