Question

Flame cells present in the members of platyhelminthes are specialized to perform,

• A. Respiration and Osmoregulation
• B. Osmoregulation and Circulation
• C. Osmoregulation and Excretion
• D. Respiration and Excretion

Answer 1

The Correct Option is C

Step 1: Understanding Flame Cells
Flame cells are specialized excretory structures found in members of the phylum Platyhelminthes (flatworms). These cells play an important role in the regulation of the internal environment of these organisms.

Step 2: Functions of Flame Cells
Flame cells are primarily responsible for osmoregulation (maintaining the balance of water and salts within the body) and excretion (removal of metabolic waste products).

• Osmoregulation: Flame cells help in regulating the water and salt balance within the organism, ensuring that it doesn't lose too much water or accumulate too many salts.
• Excretion: They also assist in the removal of waste products, similar to kidneys in more complex organisms.

Flame cells do not directly assist in respiration or circulation, as these processes are managed by other systems in flatworms.

The correct answer is (C) : Osmoregulation and Excretion.

Answer 2

The correct answer is: (C) Osmoregulation and Excretion.

Flame cells are specialized cells found in certain invertebrates, including the members of the phylum **Platyhelminthes** (flatworms). These cells play a crucial role in the processes of osmoregulation and excretion, which are essential for maintaining the internal balance of water and salts in the organism's body.

Flame cells are named for their appearance under a microscope, which resembles the flickering of a flame. Each flame cell contains a tuft of cilia that beats to create a current, helping to remove waste products and excess water from the body. This process helps in the elimination of metabolic waste and in regulating the osmotic pressure of the internal environment.

In addition to excreting waste, flame cells also help maintain homeostasis by balancing water and ions within the body, which is particularly important for organisms living in aquatic environments or in moist habitats where water balance is critical.
