Identify the type of specialised cells found in flatworms that help in osmoregulation.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Flame cells.
Flame cells are specialized cells found in flatworms (Platyhelminthes) that play a key role in osmoregulation and excretion. These cells are part of the protonephridial system, which helps remove excess water and waste materials from the body. Flame cells have cilia that beat in a wave-like motion, resembling a flickering flame, which is how they got their name. This action helps drive waste fluids through tubules and out of the body, maintaining the worm’s internal fluid balance.
