Tapeworm respires

Options

A. Through suckers
B. Through mouth
C. Through lateral pores or Sterigmata
D. Anaerobically

Answer

**Step-by-Step Solution:**

1. **Understanding Tapeworms**: Tapeworms are a type of flatworm belonging to the class Platyhelminthes. They are primarily endoparasites, meaning they live inside the host's body, often in the intestines.

2. **Digestive System**: Tapeworms lack an alimentary canal, which means they do not have a mouth or digestive tract. Instead, they absorb nutrients directly through their body surface from the host's digested food.

3. **Respiration Process**: Since tapeworms reside within the host's body, they do not have access to atmospheric oxygen. Therefore, they perform anaerobic respiration, which does not require oxygen.

4. **Anaerobic Respiration**: In anaerobic respiration, glucose is broken down without oxygen. This process can lead to the production of byproducts such as lactic acid or ethanol, depending on the specific metabolic pathways utilized by the organism.

5. **Conclusion**: The correct answer to the question of how tapeworms respire is that they respire anaerobically.

**Final Answer**: Tapeworms respire anaerobically.
