What is Flame cell in zoology?
A flame cell is a specialized excretory cell found in the simplest freshwater invertebrates, including flatworms, rotifers and nemerteans; these are the simplest animals to have a dedicated excretory system. Bundles of flame cells are called protonephridia.
What is function of flame cell?
Flame cells function like a kidney, removing waste materials through filtration. The cilia propel waste matter down the tubules and out of the body through excretory pores that open on the body surface; cilia also draw water from the interstitial fluid, allowing for filtration.
What is meant by flame cell?
: a hollow cell that has a tuft of vibratile cilia and is part of some lower invertebrate excretory systems (as of a platyhelminthic worm)
Do Aschelminthes have flame cells?
Complete answer: They function like kidneys. Many invertebrates such as flatworms use a nephridium as their excretory organ. At the end of each blind tubule, the nephridium is present which is a ciliated flame cell. -The excretory system aschelminthes contains gland cells or of canals or sometimes both of them.
What is a flame cell Multiple Myeloma?
Flame cells are atypical plasma cells with irregular cytoplasmic projections that stain bright purple-red with Wright-Giemsa stain. They are usually associated with IgA myeloma but may be seen in non-IgA myelomas, MGUS, as well as reactive plasmacytosis.
What is Flame cell Class 11?
Flame cells is a specialised excretory cell found in the simplest freshwater invertebrates, including flatworms. They function like a kidney, removing waste material. Flame cells is a specialised excretory cell found in the simplest freshwater invertebrates, including flatworms.
What are flame cells Class 11?

Flame cells function like a kidney, removing waste materials. Bundles of flame cells are called protonephridia.
Why flatworms are called acoelomates?
Due to the lack of a body cavity, flatworms are known as acoelomates. Flatworms have an incomplete digestive system. This means that the digestive tract has only one opening. Digestion takes place in the gastrovascular cavity.
Do sponges have flame cells?
This is possible because like sponges, the vast majority of their cells are in contact with the environment. They have what are termed “flame cells” (or “protonephridia”) located all along two highly-branched tubules that run the length of the body.
Where are Mott cells seen?
Mott cells can be seen in plasma cell dyscrasias and reactive plasmacytoses such as chronic inflammatory conditions, autoimmune-mediated diseases (eg, Hashimoto’s thyroiditis and rheumatoid arthritis), and rare conditions like Wiskott-Aldrich syndrome and von Recklinghausen’s neurofibromatosis.
Where are Mott cells found?
plasma cell
Mott cells are plasmocytes with multiple immunoglobulin inclusions (Russell bodies), giving them the classic “bunch of grapes” aspect. These cells can be found in plasma cell dyscrasias and reactive plasmacytosis, such as chronic inflammatory conditions or infections.
