Where are Solenocyte cells found?
Solenocytes also known as flame cells are excretory structures found in Platyhelminthes. They are meant for excretion and osmoregulation. The solenocyte carries a flagellum, which wafts excretory products along the tubule. The walls of the tube are thin and consist of pillar-like rods.
What is the function of solenocytes?
Solenocytes are a type of long, narrow, flagellated cell that functions in excretion of nitrogenous wastes and occurs in a variety of organisms, including certain annelids and molluscs.
What is the meaning of solenocytes?
Definition of solenocyte : any of various modified tubular flagellated cells occurring in the nephridia of the larvae of some annelids, mollusks, and rotifers and of a few lancelets.
What is the excretory organ of amphioxus?
The excretory organs of Amphioxus occur as segmentally arranged structures throughout the pharyngeal region and may be divided into three components: the solenocytes, the renal tubule, and the renal glomerulus. The solenocytes possess foot processes that rest upon the coelomic surface of the ligamentum denticulatum.
What is solenocytes in zoology?
noun Zoology. a type of long, narrow, flagellated cell that functions in excretion of nitrogenous wastes and occurs in a variety of organisms, including certain annelids and mollusks.
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.
Which of the following has excretory organ called solenocytes?
flatworms
Molluscs. Hint: Solenocyte is an elongated cell derived from the mesoderm which constantly moves along with flagellum. It forms the excretory system of the flatworms.
What is the excretory organ of spider?
The coxal glands are excretory organs that lie in the prosoma, and open to the outside at the coxae of the walking legs. In primitive spiders, such as the Mesothelae and the Mygalomorphae, two pairs of coxal glands open onto the posterior side of the first and third coxae.
What is the excretory organ of cockroach?
Malpighian tubules
Ans. Malpighian tubules are the excretory system of cockroaches.
What is the function of Protonephridia?
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, as illustrated in Figure 22.10a.
What is difference between protonephridia and nephridia?
Protonephridia are composed of many flame cells that are ciliated cells used in excretion. Metanephridia are composed of cells that have an internal opening known as nephrostome and an external opening known as nephridiopore. Nephridia are important structures in excretion.
Which has Nephridia for excretion?
Annelids
So, the correct answer is ‘Annelids’.
What is the excretory organ of fish?
kidney
The primary excretory organ in fishes, as in other vertebrates, is the kidney. In fishes some excretion also takes place in the digestive tract, skin, and especially the gills (where ammonia is given off).
Does cockroach have kidney?
Malpighian tubules constitute the excretory organs of cockroach and other insects. Nephridia are the most generally found excretory organs in earthworms. Flame cells are the platyhelminth excretory organs.
Which animal has flame cells?
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.
Does human kidney have nephridia?
Human kidney has about 1 million nephridia.
