Question

Which of the following is the excretory organ in Taenia?
A. Flame cells
B. Nephridia
C. Nephrons
D. Kidneys

Answer 1

The pork tapeworm, Taenia solium , has a place with the cyclophyllidean cestode family Taeniidae. It is found all through the world and is generally regular in nations where pork is eaten. It is a tapeworm which has humans as its conclusive host and frequently pigs as the middle of the road or auxiliary host.

Step by step answer: A flame cell is a particular excretory cell found in the easiest freshwater spineless creatures, including flatworms (Platyhelminthes), rotifers, and nemerteans. They have a tuft of cilia which consistently beats to clear the nitrogenous waste which gives an appearance of consuming flame. Taenia is the normal tapeworm having a place with phylum Platyhelminthes. Along these lines, the right answer is choice A.
The nephridium (plural nephridia) is an invertebrate organ, found two by two and playing out a capacity like the vertebrate kidney. A metanephridium (meta = "after") is a sort of excretory organ found in numerous kinds of spineless creatures, for example, annelids, arthropods and mollusca. So, option B is incorrect.
The nephron is the utilitarian unit of the kidney. The glomerulus and tangled tubules of the nephron are situated in the cortex of the kidney, while the gathering conduits are situated in the pyramids of the kidney's medulla. So, option C is incorrect.
The kidneys are two bean-molded organs found in invertebrates. They get blood from the combined renal courses; blood exits into the matched renal veins. So, option D is incorrect.
Hence, option A is correct.

Note: Their excretory framework comprises two tubules associated with an exceptionally expanded pipe framework that prompts pores found up and down the sides of the body. The filtrate is emitted through these pores. The cells in the tubules are called flame cells (or protonephridia) in light of the fact that they have a bunch of cilia that resembles a flashing flame when seen under the magnifying lens. Flame cells work like a kidney, eliminating waste materials through filtration. Flame cells are found in freshwater spineless creatures, for example, flatworms, including parasitic tapeworms and free-living planaria
