2. Epithelial Tissue POGIL
1. All of the diagrams represent a type of tissue called epithelial tissue. What characteristics does each type of epithelial tissue share?
Stratified cuboidal
Simple cuboidal
Simple columnar
Stratified columnar
Simple squamous
Stratified squamous

3. Epithelial Tissue POGIL
2. The starred portion of each diagram represents something called the basement membrane, whereas the blue cells are epithelial cells. What is a basement? Why do you think the term “basement membrane” is used to describe the tissue?

5. Column 2
Column 1
4. What is the difference between the epithelial tissue in the first column and the epithelial tissue in the second column?
5. What do you think the roots “simple” and “strat” mean?
Stratified cuboidal
Simple cuboidal 1
Simple columnar
Stratified columnar
Simple squamous
Stratified squamous

6. Row 1
6. As you have seen before, epithelial tissue is named for if it is single or multi-layered. Look at the rows of diagrams. In addition to being named for layers, what else is a feature used in naming epithelial tissue?
Stratified cuboidal
Simple cuboidal
Row 2
Simple columnar
Stratified columnar
Row 3
Simple squamous
Stratified squamous

7. Row 1
7. What shape are cuboidal cells? What about columnar cells?
8. The root “squam” means scale. Do you think squamous is a good name for the type of epithelial tissue shown in row three? Explain your answer.

Row 2
Simple columnar

Row 3

9. Come up with a definition for pseudo stratified columnar epithelial tissue.

10. A pseudonym is a false name. Sometimes famous actors use pseudonyms when they make reservations so that they can stay incognito. Pseudoscience describes things that masquerade as science that are not really science. For example, astrology (horoscopes, etc.) is a pseudoscience. The root pseudo means false. Why is this a good root to describe pseudo stratified columnar epithelium?

10. Name that Epithelial Tissue
11. Is the epithelial tissue below simple or stratified? What shape would you say the cells are?

14. Is the epithelial tissue below simple or stratified? What shape would you say the cells are?

14. Column 2 Column 1 Stratified cuboidal Simple cuboidal Simple columnar
15. The type of epithelial tissue present is based on the needs of the organ. For example, the alveoli in the lungs (tiny air sacs) are composed of simple squamous epithelium while the skin, lining of the mouth, anus, and vagina is composed of stratified squamous epithelium. Why do you think alveoli need to have simple squamous epithelium while skin needs stratified?
