transitional epithelium is the modified form of staratified epithelium this epithelium are mostly found in the organ of urinary system and is also called urothelium. it has got especial property exapanding and contracting for example in case of urinary bladder . in transitionna epithelium surface cell are umbrella shape and is covered by glycoprotein
but in case of stratified squamous epithelium surface cell is flat. has no capacity of cantractying and dilating .
if it stratified squamous non keratinized than surface cell has nucleus no keratin covering
if it is stratified squamous keratinized than surface cell has no nucleus and is covered by keratin
this both type of stratified epithelium are mostly found in those places where body suffer with friction for example esophagous , dermis of skin .
this both type of stratified epithelium has special proprty by which surface layer cell is replaced by new layer of cell due to mitosis division of basal layer cell

Transitional epithelium contains cells that are flattened and cells that are cuboidal; hence the name "transitional". Stratified squamous is different from transitional epithelium since the shape of the individual cell is more hexagonal and contains flattened cells. Transitional epithelium have the capacity to stretch and flatten.
Transitional epithelium differs structurally from other stratified squamous epithelia because it is formed of rounded or "plump" cells with the ability to slide over one another to allow the organ to be stretched.
transitional epithelium can change numbers of layers and cell shaper when it's full(blader)
Epithelial cells of the Pulmonary surface, + epithelial duct elements of Glands, Ciliary epithelium, esophageal, germinal {of Ovaries}, glandular and membranous: Cornea, larynx, nasopharynx, small intestine, stomach, olfactory, pigments of the Retina. As well, here are the rest: Pseudostratified, seminiferous, simple, simple columnar, simple cubical, simple cuboidal, simple squamous, stratified, stratified columnar, stratified cuboidal, stratified squamous, surface - of stomach - , and transitional.
So, think of parts of the body where stratified and simple epithelium line.The stomach and small intestine, for example, are lined with simple epithelial tissue, but the skin, vagina and oesophagus are composed of stratified epithelial tissue.So areas where there isn't a huge amount of movement required are lined with simple epithelium (the stomach just secretes substances and the small intestine absorbs and secretes; absorption is made easier by having just the one layer). But the skin, vagina and oesophagus have to deal with a lot mechanical stress and so simple epithelium wouldn't be suitable which is why so many layers are needed; hence they are composed of stratified epithelium.Stratifed epithelia are two or more cells thick and simple epitheium are one cell thick

Epithelia cells are the first cell type that differentiate in the embryo during the 8 cell stage. Epithelia are tissues that are formed by epithelial cells. These specialized cells are differ from others by the nature of avascular, sensory, gliding surface layer, tight barrier and differs from endothelial cells. They form the major cavities of the body. These cells form lungs, kidney, kidney, pancreas and so on. Epithelia act as sensory receptors, hence they form taste buds, nose, ear, female reproductive organs and so on.
Aerobic and anaerobic are terms usually applied to bacteriae, in which we differ between different levels of "air tollerance". A squamous cell carcinoma is a neoplasm consisting of the body's own cells (allthough the cells have undergone a transformation into tumor cells). The cells in our body are aerobic (allthough they can metabolize nutrients anaerobically for a short time; the anaerobic metabolism is not efficient enough for survival). therefore the cells of a carcinoma are aerobic.

Cancer cells differ from normal cells structurally as they look majorly clumped with unusual patterns or formations. Cancer cells differ in cell activity compared to normal cells greatly as they are constantly growing and dividing while normal cells do not and stop growing and dividing when touching another cell.
Their apparent number of layers;simple epithelium with a single-layer offer less protection than Stratified epithelium having multiple layers. Also, simple epithelium functions in moving materials across its surface.
Stratified random sampling is a sampling scheme which is used when the population comprises a number of strata, or subsets, which are similar within the strata but differ from one stratum to another. One example is school children stratified according to classes, or salaries stratified by departments.A simple random sample may not have enough representatives from each stratum and the solution is to use stratified random sampling. Under this scheme, the overall sampling proportion (sample size/population size) is determined and a sample is drawn from each stratum which represents the same proportion.
simple tissue has only one layer of cells stratified has 2 to 20 or layers of cells the deepest layer attached to the basement membrane
By relating to their specific excretions. While they do share some excretory functions and products, the main function that they do not share is that stomach epithelial cells secrete hydrochloric acid.
