The outer layer of a root that contains root hairs is called the epidermis. The root hairs are extensions of the epidermal cells that increase the surface area for water and nutrient absorption from the soil. This layer plays a crucial role in the plant's ability to take up essential resources for growth and development.
Root hairs
The Cortex
Root hairs are slender outgrowths of epiblema (also known as the piliferous layer), which is the outermost layer of cells in plant roots. Epiblema helps protect the root and absorb water and nutrients from the soil, while root hairs increase the surface area available for absorption.
Hairs are produced within an organ called the hair follicle, which is located in the dermis layer of the skin. Each hair follicle contains the necessary structures for hair growth, such as the root, bulb, and papilla.
The lower epidermal layer of leaf has many holes (stomata) in it and guard cells surrounding these holes. In the roots the epidermis has many root hairs growing out of it or regions of dead root hairs where over time the roots have grown longer and the old root hairs are no longer needed to capture water. In the upper epidermis of a leaf you would see palisade cells just beneath the epidermal layer and a waxy cuticle just above.
one thousand root hairs are in a tree
is epidrmis present in root hairs
The spongy layer of ground tissue inside the epidermis of a root is known as the cortex. This region of the root is important for storage and transport of nutrients absorbed by the root hairs. It also provides structural support to the root.
No root hairs are not found on the stomata.
The region of the root where root hairs are located is called the root hair zone. It is found just behind the root tip in the zone of maturation where new cells differentiate into root hairs to absorb water and nutrients from the soil.
the inner layer ---> novanet
because absorption of water takes place by root hairs in the root
