Tissue (biology)

In biology, tissue is a cellular organizational level intermediate between cells and a complete organ. A tissue is an ensemble of similar cells from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

The study of tissue is known as histology or, in connection with disease, histopathology. The classical tools for studying tissues are the paraffin block in which tissue is embedded and then sectioned, the histological stain, and the optical microscope. In the last couple of decades, developments in electron microscopy, immunofluorescence, and the use of frozen tissue sections have enhanced the detail that can be observed in tissues. With these tools, the classical appearances of tissues can be examined in health and disease, enabling considerable refinement of medical diagnosis and prognosis.

Animal tissues

Grouped in to four basic types: connective, muscle, nervous, and epithelial. Multiple tissue types compose organs and body structures. While all animals can generally be considered to contain the four tissue types, the manifestation of these tissues can differ depending on the type of organism. For example, the origin of the cells comprising a particular tissue type may differ developmentally for different classifications of animals.

Triphosa dubitata

Triphosa dubitata, the tissue, is a moth of the Geometridae family. It is found from North-west Africa across Europe to Asia and Japan.

The wingspan is 38–48 mm. Adults are on wing from August to September depending on the location.

The larvae feed on Prunus padus, Rhamnus species (including Rhamnus frangula and Rhamnus cathartica) and Fraxinus excelsior.
