Detailed explanation-1: -Tissue is a group of cells that have similar structure and that function together as a unit. Primary types of body tissues include epithelial, connective, muscular, and nervous tissues. Epithelial tissues form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.

Detailed explanation-2: -A group of similar cells which perform a specific function is called a tissue.

Detailed explanation-3: -Complete answer: The Group of tissues performing particular functions in the body is called an organ or an organ is a structure composed of at least two or more tissue types. Each tissue performs a specific function of the body. Several organs together constitute an organ system.

Detailed explanation-4: -Epithelial and connective tissues are the same in that they are both composed of cells, contain extracellular matrix material, and are generally avascular lacking a blood supply.

Detailed explanation-5: -There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
