Which of the following is the term for tightly packed sheets of cells that cover organs and outer surfaces? a. Epithelial tissue

Epithelial tissue

Explanation:

The correct option would be the epithelial tissue.

Epithelial tissues are made up of tightly arranged cells and primarily functions as protective covers for organs and outer surfaces. Usually, a side of the component cells in epithelial tissue are in contact with organs which they are covering through a non-cellular basement membrane and the other side of the cells are free.

The non-cellular basement membrane that connects the cells in epithelial tissues to organs and surfaces is secreted jointly by the epithelial and connective tissues and usually made up of protein and carbohydrate.
