The main difference between protonephridia and metanephridia is that
A) protonephridia are involved in osmoregulation, whereas metanephridia are involved in excretion.
B) protonephridia consist of blind flame cells, whereas metanephridia consist of tubules open at both ends.
C) protonephridia are involved in excretion, whereas metanephridia are involved in osmoregulation.
D) protonephridia consist of tubules open at both ends, whereas metanephridia consist of blind flame cells.
E) protonephridia are found in annelids and metanephridia are found in flatworms.
Protonephridia
A network of tubules with ciliated structures known as flame cells that function in excretion and osmoregulation in certain invertebrates.
Metanephridia
The excretory organs of annelids and mollusks; each consists of a tubule open at both ends; at one end a ciliated funnel opens into the coelom, and the other end opens to the outside of the body.
Osmoregulation
The process by which living organisms regulate the concentration of water and solutes within their bodies to maintain homeostasis.
