The members of phylum Annelida are known as “the segmented worms”. Their body is metamerically segmented. They are triploblastic and coelomate animals. The excretory units of these invertebrates are coiled tubules, the nephridia. They help in osmoregulation.
Example: Nereis, Pheretima and Hirudinaria. Body
Symmetry: Segmented worms have the typical metameric segmentation. Their body consists of segments called somites or metameres and ring like grooves known as annuli. They have bilateral symmetry.
Mode of Respiration: Respiration in annelids occurs through the skin. In some, gills are present.
Q. Nephridia of earthworm are analogous to _______.
  • a)
    Tracheae of insects.
  • b)
    Gills of Prawn.
  • c)
    Nematoblasts of Hydra
  • d)
    Flame cells of Dugesia
Correct answer is option 'D'. Can you explain this answer?

Explanation:

Nephridia of earthworm are analogous to Flame cells of Dugesia
- Nephridia in Earthworm:
Nephridia are the excretory organs of earthworms. They are coiled tubules that help in osmoregulation by removing metabolic wastes from the body.
- Flame cells in Dugesia:
Flame cells are the excretory organs of flatworms like Dugesia. They help in osmoregulation by removing metabolic wastes from the body.
- Analogy:
Both nephridia in earthworms and flame cells in Dugesia serve similar functions as excretory organs by removing metabolic wastes. They are both involved in osmoregulation processes in their respective organisms.
- Function:
Both nephridia and flame cells help in maintaining the internal environment of the organism by regulating water and electrolyte balance, as well as removing nitrogenous wastes.
- Structural Similarities:
Although they belong to different phyla (Annelida and Platyhelminthes), nephridia and flame cells have analogous structures and functions in excretion and osmoregulation.
- Conclusion:
Nephridia of earthworms and flame cells of Dugesia are analogous excretory organs in different phyla of invertebrates, serving similar functions in maintaining internal homeostasis.
