an excretory cell with a bunch of cilia that expel wastes to the outside; the actions of the cilia somewhat resemble a flickering flame, as in certain flatworms

flame cell A specialized cell at the blind end of a nephridium that ?lters body þuids.
flora Term collectively applied to all of the plants in an area. The botanical counterpart of fauna.
flame cell Specialized hollow excretory or osmoregulatory structure of one or several small cells containing a tuft of flagella (the "flame") and situated at the end of a minute tubule; connected tubules ultimately open to the outside. See solenocyte, protonephridium.
Other materials that need to be removed from the system can be excreted through specialized cells called flame cells. Flame cells are the first appearance of excretory ducts in organisms. Flame cells have cilia that beat and filter out materials that the flatworm wants to get rid of.
The tubules have a ciliated flame cell at one end which maintains a current. Annelids have ciliated funnel-shaped nephridia which opens to the exterior. Mollusks and arthropods have similar nephridia but they are concentrated into kidneys.
Platyhelminthes have a primitive excretory system made of flame cells (also called solenocytes), excretory ducts and excretory pores.
