What does Piliferous layer mean?
The region of the epidermis of a root, a short distance from the tip, that produces abundant root hairs and is involved in the uptake of water and nutrients.
What is Piliferous?
Definition of piliferous : bearing or producing hairs — compare pilose.
What is the function of root hair tissue?
The main function of root hairs is the uptake of water and nutrients from the rhizosphere.
Why are roots covered in root hairs?
The root hairs are long which allows them to penetrate between soil particles, and prevent harmful bacterial organisms from entering the plant through the xylem vessels. Increasing the surface area of these hairs allows plants to be more efficient in absorbing nutrients and establish relationships with microbes.
Where is the Piliferous layer?
epidermis
piliferous layer (root-hair zone) The region of the epidermis of a root, a short distance from the tip, that produces abundant root hairs and is involved in the uptake of water and nutrients.
Is Piliferous a word?
having or producing hair.
Why do you think that root hairs are produced only on the parts of the root system that have stopped growing?
Root hairs occur mainly on developed parts of the root system because these parts are structurally stable and able to start absorbing water and…
Which of the following plant does not show tap roots?
Option (c) is correct. Maize are monocot plants. Flowers of maize have parallel venation. It means that maize plant have fibrous roots and does not have tap roots.
What is the function of the piliferous layer?
Piliferous layer is the part of the root epidermis that bears root hairs. It extends over a region about 410 mm behind the root tip. Beyond this, the piliferous layer is sloughed off to reveal the hypodermis. It is involved in the uptake of water and nutrients.
What is the outermost layer of the root?
Epiblema or epidermis is the outermost layer of roots, composed of a compact layer of thin-walled, polygonal parenchymatous cells with no intercellular spaces. Some of the epidermal cells of both monocot and dicot roots produce specialized root hairs present in the maturation zone.
Why is the piliferous layer of the epidermis easily peeled off?
Beyond this, the piliferous layer is sloughed off to reveal the hypodermis. It is involved in the uptake of water and nutrients. Epidermis of root is always single layered in thickness and never covered by cuticle therefore, it is easily peeled off so called as piliferous.
What is the function of root in a plant?
The root is commonly the underground part of the plant body that helps to anchor it down to the ground and absorbs water and minerals from the soil. Sometimes the root changes their shape and gets modified to store reserve food as found in sweet potato, radish, and carrot plant.
