The cells in the retina and the cells that line your air-passages have only one thing in common: they are often seen in close proximity to each other in homework questions about what the relationship between retinal cells and air-passage cells might be.
Epithelial tissue or more simply epithelium covers and lines body surface and forms glands. Cells of epithelium are very set very close to each other, neighbouring cells are held together by cell junctions or desmosomes. The desmosomes of macula adherens made of tonofibrils. The epithelial tissue rests on a thin extracellular basement membrane, secreated partly by epithelial cells and partly by underlying connective tissue. Epithelial cells may have microvilli, sterocilia, kinocilia or flagella. They are of two types: connective and lining epithelium and gladular epithelium
Epithelial-like cells in sponges help control filter feeding by lining the channels and chambers where water is drawn in and filtered. These cells have specialized structures like microvilli and cilia that aid in capturing food particles as water flows through. By regulating the flow of water through these channels, the epithelial-like cells play a crucial role in efficient filter feeding in sponges.
Epithelial cells tend to have a rectangular shape. These cells line the surfaces and cavities throughout the body and have a protective function. Their rectangular shape allows for close packing and provides structural support.
Moderate epithelial dysplasia is a histological term used to describe abnormal changes in epithelial cells that are considered to be between mild and severe dysplasia. These changes are considered precancerous and may require close monitoring or treatment to prevent progression to cancer. Treatment options may include surgery or other interventions depending on the location and extent of the dysplasia.
Both. There are too many different types of cells to mention but for example, skin or epithelial cells are obviously stuck very close together. Blood platelets, or cells, are free moving for obvious reasons. In order to answer this question more correctly you need to be more specific.

Tampa is close to Tampa Bay and the Gulf of Mexico.
it is produced by interstitial fibroblasts in the kidney in close association with peritubular capillary and tubular epithelial cells

This is your bodys natural defense to protect the eyes. It is a reflex.

A tight junction appears as a series of interlocking strands that encircle the cell, effectively sealing adjacent epithelial or endothelial cells together. This structure resembles a belt or a band around the cells, preventing the passage of substances between them and maintaining the integrity of tissue barriers. Under an electron microscope, tight junctions are characterized by their close apposition of cell membranes and specialized proteins, such as claudins and occludins, that facilitate their function.
yes they are very close together
