Epithelial cells are generally divided into two main groups:
Simple and Stratified
Simple epithelium is of a single cell thickness and every cell is in contiguous contact with the basal lamina by hemi desmosomes (cell anchors). These can be further subdivided into other groups.
Stratified epithelium is multilayered arranged into 'strata' and is found in the body where the cells in contact with the lumen are lost frequently due to mechanical or chemical stressers (e.g small intestine or skin cells). The cells are held together by intermediate filaments and desmosomes. These can be further subdivised into other groups.
The features of the groups vary widely depending on the sub-specialisation e.g. stratified squamous keratinised epithelium makes up skin cells and has very different features to simple cuboidal epithelium such as that found in the testicle.

Epithelial cells are classified as?
A group of epithelial cells organized to perform a common function would be a tissue.
What would would a group of ciliated cells be called?
ciliated epithelial tissue
Which of the following would be produced by meiosis red blood cell cells of the stem in plants sperm cell or epithelial cell?
Meiosis would produce sperm cells and epithelial cells in plants. Red blood cells do not undergo meiosis, as they lack a nucleus and are not capable of dividing.
Epithelial cells are specialized for all the following functions?
Without knowing what the functions are a person will have difficulty knowing which are specialized for epithelial cells. Including the functions would insure that a person will provide the correct answer.
If you examine a population of intestinal epithelial cells under a microscope most of the cells would appear in what phase of the cell cycle?
. be in mitosis.

What is tissue that is composed of closely packed cells with little extracellular material?
Epithelial tissue are closely connected and have a basal membrane, even though not all epithelial cells are necessarily connected to the basal membrane. The so called simple epithelial tissue subgroup does.
Why the presence of epithelial cells in urine are reason for pelvic cavity pain?
Epithelial cells in urine would be a pretty good indicator of an infection, this the pelvic pain. ( Maybe kidney or Bladder)

If you were looking at specialized cells from a tissue how would you know if they came from a sample of epithelial?
Cells would fit closely together to form a barrier

What side of an epithelial cell is closest to the blood vessel?
I think that the bottom of epithelial cells is closest to blood vessels (if one were to look at a flat 2D image. Endothelial cells similarly would have the top of the cell closest to blood vessels.
What cells would have a greater probability of developing into cancer?
cell population that reproduces excessively and migrates
