Vedclass · Answer

(A) In the animal kingdom, different phyla have evolved specialized structures for excretion. $1$. $ 	ext{Flame cells} $ (protonephridia) are the specialized excretory structures found in $ 	ext{Platyhelminthes} $ (flatworms) which help in osmoregulation and excretion. $2$. $ 	ext{Nephridia} $ are the tubular excretory structures found in $ 	ext{Annelida} $ (segmented worms) which help in removing nitrogenous wastes and maintaining fluid balance. Therefore, the correct sequence is $ 	ext{Platyhelminthes} $ and $ 	ext{Annelida} $.
