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.

What are the growth regions of roots?
The Meristematic Region or Growing PointThis 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.FunctionThis is the region where the cells divide and where additional cells are provided for the zone of elongation.The Region of ElongationThe 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.FunctionIn this region the cells undergo rapid enlargement,i.e. the cells undergo rapid growth in length.The Root-hair RegionThe 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.FunctionThe main function of the root hairs is to increase the area of absorption of the root.The Mature RegionThe 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 .FunctionsIn this region the cells undergo differentiation into specialized cells,(e.g. xylem and phloem).It also serves to anchor the plant.febbie
Can regions overlap?
Yes, regions can overlap when they share boundaries or have areas that are common to both regions. Overlapping regions are common in geospatial analysis, political boundaries, and environmental studies where features can exist in multiple regions simultaneously.
The two basic types of regions are?
The two basic types of regions are formal regions and functional regions. Formal regions are defined by a common characteristic, such as language or political boundaries. Functional regions are defined by their connections or interactions, such as a city and its surrounding suburbs.
What are different types of cultural regions?
One culture region would be Southwest Asia and North Africa who have a common language and religion which is also Arab
What are the differences between covered and uncovered regions?
Covered regions have some sort of protection or shelter, such as a roof or canopy, while uncovered regions are open to the elements. Covered regions offer protection from sun, rain, and wind, while uncovered regions are exposed to weather conditions.
Where on a plant would you find meristematic tissue?
The meristematic tissue on a plant is found at the regions of active growing points such as shoot and root apices and intercalary regions having cambial activity.
What are the tissue cells of a plant organ?
Plant tissue systems fall into one of two general types: meristematic tissue and permanent (or non-meristematic) tissue. Cells of the meristematic tissue are found in meristems, which are plant regions of continuous cell division and growth.
From where do all plant tissues originate?
All plant tissues originate from meristematic cells, which are found in the growing regions of the plant such as the root and stem tips. These meristematic cells continually divide and differentiate into various types of plant tissues, including vascular, epidermal, and ground tissues.
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.
What are the Properties of meristematic tissue?
Meristematic tissues are cells or group of cells that have the ability to divide. These tissues in a plant comprise small, densely packed cells that can keep dividing to form new cells. Meristems have the following characteristics:The cells are small,The cells walls are thin,Cells have large nuclei,Vacuoles are absent or very smallThere are no intercellular spaces
Why do meristematic tissues lack vacuoles?
Meristematic tissues are tissues present in areas of rapid division of the plant like the root stem and leaves.The presence of a vacuole will not let them divide and hence they dont have vacuoles. the meristematic cell divides to form 1 permanent cell with a vacuole and another meristematic cell and so the cycle goes on .
Are undifferentiated cells found in meristematic tissue?
Yes, undifferentiated cells are found in meristematic tissue. Meristematic tissue is responsible for plant growth and contains actively dividing cells that have the ability to differentiate into various types of plant tissues.
What is the difference between meristematic and permanent tissue?
Meristematic tissues have the capacity to divide while permanent tissue lost the capacity of division. Meristematic tissue have thin cellulose walls while permanent tissue has a thick cellulose wall.
Growthing points possess?
Meristematic cells
In which part of a pine tree stem is meristematic tissue located?
They are meristematic cambium cells located in a layer just inside the bark of trees and shrubs.
Why growth occures in certain regions rather than throughout the plant?
Because meristem is located either at the apical region or intercallary region and growth needs cellular division which occurs only in the meristematic cells.
What is the difference between meristematic tissues from permanent tissues?
Meristematic tissues are responsible for cell division and growth, leading to plant growth and development. Permanent tissues are derived from meristematic tissues and have specialized functions like storage, support, and transport. Meristematic tissues are found at the growing tips of roots and shoots, while permanent tissues are found throughout the plant body.
