Which of the root functions is carried out by root hairs?
the function known as elongation
Which section of the root has root hairs?
the root hairs are located in the region above the root tip.
Explain are root hairs found all over a root?
Root hairs are found on the tips of the roots.
How does auxin produce phototropism?
Auxin accumulates on the lower surface of the root and inhibits elongation of cells in that region.
Is epidermis present in root hairs?
is epidrmis present in root hairs
Which of the root functions is carried out by root hairs?
the function known as elongation
Does the elongation of the cells in the region of elongation increase the root length?
no
Which section of the root has root hairs?
the root hairs are located in the region above the root tip.
Are Root hairs are found mostly on the stomata.?
No root hairs are not found on the stomata.
Explain are root hairs found all over a root?
Root hairs are found on the tips of the roots.
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
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 growth regions of roots?
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.
Are root hairs found mostly on the stomata?
No root hairs are not found on the stomata.
How does auxin produce phototropism?
Auxin accumulates on the lower surface of the root and inhibits elongation of cells in that region.
What region is responsible for the root hairs growth?
Root hairs grow longer as they age (similar to how we grow taller as we age). Since the older (and therefore longer) root hairs are at the distal end of the root cap (towards the base of the root), it creates a tapering appearance. In other words, as you move from the base of the root towards the root cap, the root hairs become shorter since they are younger.
What are the three growth zones of roots?
This is the organization of roots from the base closest to the plant itself to the tip of the root: zone of maturation - cells specialize to carry particular functions (root hairs present) zone of elongation - rows of newly produced cells elongate zone of cell division - new cells being produced root cap - covers the growing tip
