What are the flame cells of flatworms called?
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. Flame cells function like a kidney, removing waste materials. Bundles of flame cells are called protonephridia.
What do flame cells do in flatworms?
(2) Flatworms have an excretory system that consists of two tubules. The cells in the tubules are called flame cells; they have a cluster of cilia that propel waste matter down the tubules and out of the body.
What phylum contain flame cells?
phylum Platyhelminthes
Flame cells are excretory organs, present in the phylum Platyhelminthes (flatworms).
What is meant by flame cell?
Definition of 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)
How does the flame cell function in a planarian?
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.
Are planaria hermaphrodites?
Planarians swim with an undulating motion or creep like slugs. Most are carnivorous night feeders. They eat protozoans, tiny snails, and worms. All are simultaneous hermaphrodites; i.e., functional reproductive organs of both sexes occur in the same individual.
What is the role of flame cells in liver fluke?
Liver fluke Flame cells They are specialized cells in Platy helminthes which helps in osmoregulation and excretion. These are also called protonephridia.
In which flame cell is present?
A flame cell is a specialized excretory cell found in the simplest freshwater invertebrates, including flatworms (Platyhelminthes). They function as a kidney, removing waste materials.
What are flame cells 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. It is a hollow cup shaped cell containing a bunch of cilia, whose movement draws in waste products and wafts them out through a tubule.
What type of reproduction is planaria?
Asexual freshwater planarians reproduce by tearing themselves into two pieces by a process called binary fission. The resulting head and tail pieces regenerate within about a week, forming two new worms.
Why is planaria called hermaphrodite?
All planarians are hermaphrodites, so their reproductive system has a male and a female part. Both parts communicate with the surface of the body via a single opening called gonopore, which is located on the ventral side of the posterior half of the body.
What is common amongst tapeworm liver fluke and planarian?
They all have flattened bodies.
