Why protonephridia are called flame cells?

Why protonephridia are called flame cells?

The cells in the tubules are called flame cells (or protonephridia) because they have a cluster of cilia that looks like a flickering flame when viewed under the microscope. Flame cells function like a kidney, removing waste materials through filtration.

What is the difference between protonephridia and flame cells?

Protonephridia form a network of tubules that only has an external opening and is devoid of an internal opening. These ends of the protonephridia are referred to as flame cells. These flame cells can either be flagellated or ciliated. Ciliated flame cells are involved in osmoregulation.

Which of the following is correct about protonephridia or flame cells?

Bundles of flame cells are called protonephridia. The function of the solenocyte is the removal of nitrogenous waste from the body. Complete answer: The simplest freshwater invertebrates, which includes flatworms, rotifers, and nemertean consist of a specialized type of excretory cell known as flame cells.

What are flame cells where do they occur?

Flame cells are the excretory organs of the phylum platyhelminthes. They are found in excretory ducts/protonephridia.

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.

What is the function of Parapodia and flame cells?

Parapodia are lateral appendages, which help in swimming. Flame cells are excretory organs and help in osmoregulation and excretion.

What is difference between Protonephridia and Nephridia?

Both are excretory organs. protonephridia ,it found in platyhelminthes while nephridia is excretory organ of annelida.

What is the function of Protonephridia?

The function of the protonephridia is the same as in most excretory organs: after ultra filtration a more or less selective resorption of substances from the lumen occurs. This reabsorption is supported by the large surface of the channel cell.

What is flame cells give example?

A flame cell is a specialized excretory cell found in the simplest freshwater invertebrates, including flatworms (except the turbellarian order Acoela), rotifers and nemerteans; these are the simplest animals to have a dedicated excretory system. Flame cells function like a kidney, removing waste materials.

What is Flame cells give example?

What class has flame cells?

Platyhelminthes class
Acoelomate animals with flame cells are A Platyhelminthes class 11 biology CBSE.

Do Cnidaria have flame cells?

So cnidarians can also simply diffuse their metabolic wastes out. Each flame cell contains a group of cilia that look like a flame, hence the name of the structure, which serve to propel waste out from the tubules into the environment, through pores in the body surface called nephridiopores [1].

Which is the correct answer protonephridia or flame cells?

In Platyhelminthes, the excretory system is consists of peculiar flame cells or protonephridia which are meant to excretion and osmoregulation. Ammonia is the chief excretory waste. Thus, the correct answer is (A).

Where are protonephridia found in the human body?

Protonephridia are cup-shaped structures found in organisms belonging to the phyla Platyhelminthes, Nemertea, Rotifera, and some Chordates such as lancelets. Protonephridia are one of the most primitive types of cells that evolved to function as excretory cells.

How are protonephridia different from other excretory cells?

Protonephridia are one of the most primitive types of cells that evolved to function as excretory cells. Protonephridia form a network of tubules that only has an external opening and is devoid of an internal opening. These ends of the protonephridia are referred to as flame cells. These flame cells can either be flagellated or ciliated.

What are the ends of the protonephridia called?

Protonephridia form a network of tubules that only has an external opening and is devoid of an internal opening. These ends of the protonephridia are referred to as flame cells. These flame cells can either be flagellated or ciliated.
