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.

What are the regions of the meristematic?
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.
How do tree roots damage rocks?
Tree roots can grow to be very big and powerful causing damage to rocks, cement, and other such materials. Tree roots damage rocks by causing them to crack or become crushed under their weight.
In What regions of the world have issues with water?
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.
What is the difference between these two regions that cause the difference in fertility rates?
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.
What kind of growth is the human population in?
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.
What are the regions of the meristematic?
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.
Why are roots a good place to study the cell cycle?
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.

A plant form new tissues at the tips of its roots and stems the new tissues growth is a direct result of?
The growth of new tissues at the tips of roots and stems in plants is the direct result of cell division and elongation in the meristematic regions known as the apical meristems. These regions contain actively dividing cells that give rise to new cells, enabling the plant to grow in length. This process is crucial for plant development and overall growth.
What are two types of merestemetic tissues?
Two types of meristematic tissues are apical meristem, located at the tips of roots and stems, and lateral meristem, found in the lateral regions of stems and roots. These tissues are responsible for the growth and development of plants.
What is the function of quiescent centers in roots?
Quiescent centers in roots are regions of cells that can divide and differentiate into various root tissues. They play a crucial role in root development by replenishing the pool of stem cells and maintaining the growth and regeneration of roots throughout the plant's life cycle.
Cells that multiply and produce growth at various parts of a plant are what?
Meristematic cells are responsible for cell division and growth in plants. These cells are found in regions such as the tips of roots and shoots, where they continuously divide to produce new cells for plant growth and development.
How do plant hormones control the growth of roots and shoots?
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.
Acids and the growth of plants' roots cause which type of weathering?

Meristems are regions of what?
These regions, where cells continuously divide, are where plant growth originates.
What is apical growth?
It is when growth occurs at the tips of roots and shoots of a plant
