Excretory system of platyhlminthes consists of___________?
Correct answer: B. Flame cells
- A. Nephridia
- B. Flame cells
- C. Malpighian tubules
- D. Nephrons
Explanation
Flatworms remove excess water and wastes through protonephridia containing flame cells, whose beating cilia drive fluid through tubules. Students may choose nephridia because annelids use them for excretion, but nephridia are not the excretory structures of platyhelminths.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
