In platyhelminthes, the excretory organs are

Options

A. Nephridia
B. Nephrons
C. Flame cells
D. Archaeocytes

Answer

**Step-by-Step Solution:**

1. **Identify the Organism Group**: The question asks about the excretory organs in Platyhelminthes, which are commonly known as flatworms.

2. **Understand the Excretory System**: In Platyhelminthes, the excretory system is specialized for the removal of waste materials from the body.

3. **Recognize the Excretory Organs**: The specific excretory organs in Platyhelminthes are called **flame cells**. These cells function similarly to kidneys in other organisms, helping to filter and excrete waste.

4. **Differentiate from Other Options**:
- **Nephridia**: These are found in annelids (like earthworms) and serve a similar function to kidneys but are not present in Platyhelminthes.
- **Nephrons**: These are the basic structural units of kidneys found in mammals, not in flatworms.
- **Archaeocytes**: Also known as amoebocytes, these are found in sponges and have different functions; they are not excretory organs.

5. **Conclusion**: Based on the information, the correct answer to the question is that the excretory organs in Platyhelminthes are **flame cells**.
