Which excretory system contains structures called flame bulbs that function in filtration?
A
Metanephridia
B
Malpighian tubules
C
Kidneys
D
Nephrons
E
Protonephridia
Verified step by step guidance1
Begin by understanding the function of excretory systems in organisms, which is to remove waste products and maintain homeostasis.
Identify the different types of excretory systems mentioned: Metanephridia, Malpighian tubules, Kidneys, Nephrons, and Protonephridia.
Learn about Protonephridia, which are a type of excretory system found in certain invertebrates like flatworms. They consist of a network of tubules with flame bulbs at the end.
Understand the role of flame bulbs in Protonephridia. Flame bulbs are specialized cells that use cilia to create a current, drawing in waste fluids from the surrounding tissues for filtration.
Recognize that the presence of flame bulbs is a distinctive feature of Protonephridia, setting them apart from other excretory systems like Metanephridia, Malpighian tubules, Kidneys, and Nephrons.
