Facts about Tissue

Cells work together harmoniously in a tissue to perform a function(s), such as epithelial tissue in the stomach producing the enzyme pepsin to help with digestion, or muscle tissue providing movement.

The study of tissue is known as histology, or, in connection with disease, histopathology.

Each cell not only performs actions for its own maintenance, self-preservation, and self-strengthening, but also performs specific actions that contribute to the larger entity, the tissue and the body.

Biological tissue is an aggregation of interconnected, morphologically, and functionally similar cells, and associated intercellular matter, that together perform one or more specific functions within an organism.

Plant tissues are categorized broadly into four tissue systems: the dermal tissue (or epidermis), ground tissue (or fundamental tissue), vascular tissue, and meristematic tissue.
