What is the outer layer of its leaf called and what is its function?
The outer layer of a leaf is called the epidermis (from a Greek word meaning "over-skin"). Its function is to protect the insides of the leaf, which carry out the chemical reaction known as photosynthesis.
What is the function of palisade in the leaf?
the palisade layer is where photosynthesis is carried out
What are the differences between pseudostratified columnar epithelium and stratified columnar epithelium in terms of their structure and function?
Pseudostratified columnar epithelium is a single layer of cells that appear to be layered due to varying cell heights, while stratified columnar epithelium has multiple layers of cells. Pseudostratified columnar epithelium is found in the respiratory tract and functions in secretion and absorption, while stratified columnar epithelium is found in the male urethra and functions in protection.
What is the structure of the simple columnar epithelium?
Simple = One layer Columnar = tall (column like) cells Epithelium = Lining, covering, and glandular tissue Simple columnar epithelium = A single layer of tall cell tissue
What layer of the digestive tract is composed of stratified and columnar epithelium?
The layer of the digestive tract that is composed of stratified and columnar epithelium is the mucosa. This layer is responsible for absorption and secretion in the digestive system.
What is the outer layer of the leaf called and what are its functions?
The outer layer of a leaf is called the epidermis (from a Greek word meaning "over-skin"). Its function is to protect the insides of the leaf, which carry out the chemical reaction known as photosynthesis.
What is a single layer long and narrow in structure?
columnar
Which epidermal layer has single layer of columnar cells?
The epidermal layer with a single layer of columnar cells is the stratum basale (basal layer). This layer is located at the bottom of the epidermis and contains basal cells that constantly divide to replenish the upper layers of the skin.
What is the outermost layer of the root stem or leaf?
The outermost layer of a root is called the epidermis. It is a single layer of cells that protects and covers the root. In stems and leaves, the outermost layer is also called the epidermis, and it serves a similar protective function.
Function of columnar cells?
Absorption , protection .
What type of tissue has a key function of protection and absorption and is classified according to the shape and layer of cells?
Epithelial tissue has a key function of protection and absorption. It is classified based on the shape and layer of cells. Shapes include squamous, cuboidal, and columnar, while layers can be simple (single layer) or stratified (multiple layers).
What structures are found in the palisade layer in the mesophyll?
Lying just beneath the cuticle layer on a leaf, the palisade layer resides very close to the surface. The palisade layer is critical to growth because it is the layer of the leaf that contains the chloroplast.
