Why is the region of elongation of the root relatively shorter than that of the stem?
This is because the root's primary function is to absorb water and nutrients, which can be achieved more efficiently with a shorter elongation zone. In contrast, the stem requires a longer elongation zone to support the plant's growth and facilitate its ability to reach sunlight for photosynthesis.

Why are root hairs not found in the elongation region?
Root hairs are specialized structures that develop near the root tip to increase surface area for absorption of water and nutrients. In the elongation region of the root, cells are actively dividing and elongating to increase root length, so there is limited space and energy for the formation of root hairs in this region. Root hairs are more prevalent in the mature region of the root where cells are specialized for absorption.
What is the effect of auxin on root called?
The effect of auxin on root growth is called root initiation or root elongation. Auxin promotes cell division and cell elongation in the root, leading to increased root growth.
Which process is directly responsible for root growth in plants?
The process directly responsible for root growth in plants is called cell division, specifically in the root apical meristem. This region contains undifferentiated cells that continuously divide, allowing for the elongation and development of roots. Additionally, the process of elongation, where newly formed cells increase in size, contributes to root growth. Auxins, a class of plant hormones, also play a key role in regulating both cell division and elongation in roots.
New root cells become longer mainly by?
New root cells become longer mainly by cell elongation, which is driven by the uptake of water and expansion of the cell walls. This process is regulated by hormones such as auxin and gibberellins, which promote cell elongation in roots. Additionally, the orientation of cell division also plays a role in root elongation.
What is the function of elongation?
The cells produced by mitosis undergo a period of elongation in the direction of the axis of the root. It is at this time that they are sensitive to gravity and respond with gravitropism.
Does the elongation of the cells in the region of elongation increase the root length?
no
What is the region of elongation's function?
The cells produced by mitosis undergo a period of elongation in the direction of the axis of the root. It is at this time that they are sensitive to gravity and respond with gravitropism.

What are the four regions of roots?
the four regions of the root are root cap, cell division, elongation and specialization
What zone follows the zone of cells division in a root tip?
Elongation
What is the function of elongation?
The cells produced by mitosis undergo a period of elongation in the direction of the axis of the root. It is at this time that they are sensitive to gravity and respond with gravitropism.
What are roots of the region?
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
Which of the root functions is carried out by root hairs?
Root hairs are mainly responsible for absorbing water and nutrients from the soil.
What zone of a root tip increases the surface area for water and dissolved mineral uptake?
The zone of a root tip that increases surface area for water and mineral uptake is the root cap region, specifically the zone of maturation or elongation where root hairs are formed. Root hairs are small, finger-like projections that significantly increase the root's surface area for absorption.
What portion of a root gets elongated?
The zone of elongation occurs when the cells in this zone stretch and lengthen as small vacuoles within the cytoplasm coalesce and fill with water. One or two large vacuoles occupy almost all of the cell volume in fully elongated cells. Cellular expansion in this zone is responsible for pushing the root cap and apical tip forward through the soil.
