As a halophyte, the salt it absorbs is excreted from specialised cells (which are not stomata) on the leaf surface.
The nose has an area of specialised cells which are responsible for smelling (part of the olfactory system).
Water is drawn in through the oscula and expelled through the ostia after having had minute food particles removed by specialised cells.
These specialised cells convert light into electrochemical signals through the ganglion cell layer and travel along the optic nerve fibers to the brain.
When an ossicle becomes redundant, specialised cells known as phagocytes are able to reabsorb the calcareous material.
They accumulate in specialised cells or in specific parts of the plant.
In humans, this membrane contains about 10 million specialised cells, each bearing tiny hairs.
In most other nematodes, these specialised cells have been replaced by an organ consisting of two parallel ducts connected by a single transverse duct.
In culture, they can be transformed into specialised cells, such as those of muscles or nerves.
Unlike other nitrogen fixing bacteria, Trichodesmium does not have heterocysts, nor any other specialised cells for this task.
