Verified step by step guidance

Understand the basic structure and function of epithelial tissue. Epithelial tissue forms the covering or lining of surfaces and cavities in the body, and its primary function is protection, absorption, secretion, and filtration.

Recognize the key characteristic of epithelial tissue: cells are tightly packed together. This arrangement allows epithelial tissue to form effective barriers and linings.

Consider the extracellular matrix in epithelial tissue. Epithelial tissue typically has minimal extracellular matrix, which contrasts with connective tissue that often has a significant amount of extracellular matrix.

Evaluate the options given in the problem. The correct characteristic of epithelial tissue is that cells are tightly packed with minimal extracellular matrix. This is essential for its protective and selective permeability functions.

Eliminate the incorrect options: Epithelial tissue does not contain a large amount of collagen fibers (typical of connective tissue), striated muscle fibers (typical of muscle tissue), or cells that are loosely arranged with abundant ground substance (also typical of connective tissue).
