would you expect to find epithelial tissue in other organisms?
Since this is not my area of expertise, I searched Google under the key words "epithelial tissue organisms" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
Yes, epithelial tissue is found in many different organisms besides humans. Epithelial tissue lines the surfaces of organs and cavities, and it serves various functions such as protection, absorption, secretion, and sensory reception. It can be found in animals, including mammals, fish, birds, reptiles, and invertebrates such as insects and worms. Additionally, epithelial-like tissues can also be found in plants, where they function in protection and gas exchange.
To determine whether one would expect to find epithelial tissue in other organisms, we need to understand what epithelial tissue is and its role in an organism's body.
Epithelial tissue is a type of animal tissue that covers surfaces, forms protective barriers, lines body cavities and organs, and participates in functions such as absorption, secretion, and sensation. It is made up of tightly packed cells that are arranged in layers, with little to no extracellular matrix between them.
Given the importance and versatility of epithelial tissue in the functioning of animal bodies, it is reasonable to expect to find a similar type of tissue in other organisms. However, the characteristics and composition of epithelial tissues may differ across organisms depending on their specific needs and adaptations.
For example, plants have a type of tissue called "epidermis" that serves as a protective outer layer covering leaves, stems, and roots. While epidermal tissue in plants shares some similarities with animal epithelial tissue, it performs different functions and has distinct structures.
Similarly, some fungi have structures called "hyphae" that could be considered analogous to epithelial tissue in terms of their protective and absorptive functions, although they are not composed of cells in the same way as animal epithelium.
In summary, while the concept of epithelial tissue may not be directly applicable to all organisms, we can expect to find analogous structures or tissues fulfilling similar functions in various organisms, each adapted to meet the specific requirements of their respective lifestyles and environments.
