A particular cell present in the excretory system of flatworms, which helps them removing waste materials is the:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. flame cell.
In flatworms (Platyhelminthes), the excretory system consists of a network of tubules ending in specialized cells called flame cells. These cells contain cilia that beat like a flickering flame, hence the name. The ciliary movement creates a current that draws waste materials and excess water into the tubules. The collected waste is then transported through excretory canals and eliminated via excretory pores. Flame cells thus play a crucial role in osmoregulation and excretion, maintaining fluid balance in flatworms.
