Protonephridia are termed "flame cells" due to their distinctive structure, which features a tuft of cilia that resembles a flickering flame when in motion. These cilia beat to create a current, helping to filter and expel waste fluids from the organism's body. This arrangement is commonly found in certain invertebrates, such as flatworms, where it serves as a simple excretory system. The name reflects both the appearance and the function of these cells in the excretory process.

Why protonephridia are termed as flame cell?
Protonephridia are termed "flame cells" due to their distinctive structure, which features a tuft of cilia that resembles a flickering flame when viewed under a microscope. These cilia beat in a coordinated manner, creating a current that helps to move waste fluids through the excretory system of certain invertebrates, such as flatworms. The "flame" appearance is derived from the way the cilia agitate the fluid, resembling the movement of flames. This specialized feature plays a crucial role in osmoregulation and excretion in these organisms.
What is the flame-cell system in planarians?
The flame-cell system in planarians consist of specialized cells called flame cells that are part of the excretory system. Flame cells have distinctive cilia that beat rapidly, creating a flickering appearance like a flame. These cells help regulate the osmotic balance and remove waste from the body by actively pumping fluids through the excretory system.
Do Platyhelminths possess protonephridia?
Yes, Platyhelminths, commonly known as flatworms, possess protonephridia. These are simple excretory structures that function in osmoregulation and waste removal. Protonephridia consist of flame cells that create a current to help expel waste products and excess water from the body. This system is crucial for maintaining the internal environment of these organisms, especially in freshwater habitats.
What is a Cell with a nucleus and organelles called?
It is termed to be a Eukaryotic Cell.
Why excretion in planaria is also called flame cell system?
in planaria excretion takes place through diffusion,as will as have special excretory system made up of many tubule called protonephridia.protonephridia give rise to branches have special kind of cells called flame cells.flame cells is nucleated have a cavity,in the centre of cavity there are cilia.cilia undulate itself look like a flickering candle that,s why it,s calld flame cells.flame cells and tubules are full of fluid,containing waste matter dissolve in it.flame cells excrete the waste through excretory pore called nephridiopore,by undulating their cillia.
The basic excretory unit in the protonephridia of flatworms is what?
flame cell

What class of annelids have protonephridia?
Protonephridia are primarily associated with the class Turbellaria, which includes free-living flatworms, rather than annelids. However, in the context of annelids, the class Oligochaeta (such as earthworms) and the class Hirudinea (leeches) have a different excretory system involving nephridia, which are more complex than protonephridia. In summary, protonephridia are not characteristic of annelids but rather of certain other invertebrate groups.
What are excretory structures called protonephridia are found in?
Protonephridia are found in flatworms, such as planarians. These structures are responsible for excreting waste and regulating osmotic balance in these organisms.
