Dorsal pores of Earthworm are meant for passage of

Options

A. Coelomic fluid
B. Blood
C. Waste materials
D. Gametes

Answer

**Step-by-Step Solution:**

1. **Understanding Dorsal Pores**: Dorsal pores are openings found on the dorsal side (upper side) of the earthworm's body. They are present in almost all segments of the earthworm except for the first 11 segments and the last segment.

2. **Location of Dorsal Pores**: It is important to note that there is one dorsal pore in each segment of the earthworm, contributing to the overall function of these structures.

3. **Function of Dorsal Pores**: The primary function of the dorsal pores is to facilitate the passage of coelomic fluid. This fluid is essential for the earthworm's physiology.

4. **Role of Coelomic Fluid**: The coelomic fluid plays a significant role in the earthworm's body. It helps in maintaining internal pressure, transporting nutrients, and importantly, it has antibacterial properties that help to kill harmful bacteria.

5. **Analyzing the Options**: The question provides four options: coelomic fluid, blood, waste materials, and gametes. Based on the function of the dorsal pores, we can eliminate the options that do not align with the known function of these structures.

6. **Conclusion**: The correct answer to the question is that the dorsal pores of the earthworm are meant for the passage of coelomic fluid.

**Final Answer**: Coelomic fluid
