Biology Question on earthworm
The nephridia in earthworm are analogous to
A
nematoblasts of Hydra
B
flame cells of Planaria
C
gills of Prawn
D
trachea of insects.
Answer
flame cells of Planaria
Explanation
Solution
Analogous organs are organs of very disparate organisms and are superficially similar but have evolved from vastly different origins. They have same function but different structure. The nephridia in earthworm are analogous to flame cells of Planar ia since both of them have excretory functions. Nematoblasts of Hydra are organs of locomotion, food capture and anchorage. Gills and trachea are organs of respiration in prawn and insects respectively.
