Simple cuboidal epithelium is a type of epithelium that consists of a single layer of cuboidal (cube-like) cells which have large, spherical and central nuclei. Simple cuboidal epithelium is found on the surface of ovaries, the lining of nephrons, the walls of the renal tubules, parts of the eye and thyroid, and in salivary glands. [1]
English: The fine scale structure of a leaf featuring the major tissues; the upper and lower epithelia (and associated cuticles), the palisade and spongy mesophyll and the guard cells of the stoma. Vascular tissue (veins) is not shown. Key plant cell organelles (the cell wall, nucleus, chloroplasts, vacuole and cytoplasm) are also shown.

English: A simple diagram of a plant leaf cell, labelled with numbers. It shows the cytoplasm, nucleus, cell membrane, cell wall, mitochondria, permanent vacuole, and chloroplasts. Note going down the left the numbers are not sequential, this is to match the numbering on others in the series.
In plant anatomy, tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue. Epidermis – Cells forming the outer surface of the leaves and of the young plant body. Vascular tissue – The primary components of vascular tissue are the xylem and phloem. These transport fluids and ...
Simple cuboidal epithelium commonly differentiates to form the secretory and duct portions of glands. [6] Stratified cuboidal epithelium protects areas such as the ducts of sweat glands, [7] mammary glands, and salivary glands. Columnar Columnar epithelial cells are elongated and column-shaped and have a height of at least four times their width.
A brush border (striated border or brush border membrane) is the microvillus-covered surface of simple cuboidal and simple columnar epithelium found in different parts of the body. Microvilli are approximately 100 nanometers in diameter and their length varies from approximately 100 to 2,000 nanometers.
Thyroid follicular cells form a simple cuboidal epithelium and are arranged in spherical thyroid follicles surrounding a fluid filled space known as the colloid. The interior space formed by the follicular cells is known as the follicular lumen.
