Find out the incorrect match about the characters of annelida

Options

A. Longitudinal and circular muscles – help in locomotion
B. Parapodia – help in swimming
C. Malpighian tubules – help in excretion
D. Neural system – consists of paired ganglia

Answer

To solve the question of finding the incorrect match about the characteristics of Annelida, we will analyze each option provided in the video transcript step by step.

### Step-by-Step Solution:

1. **Understanding Muscle Function in Annelida**:
- The first statement mentions that longitudinal and circular muscles help in locomotion. This is true because annelids use these muscles to move by contracting and relaxing, allowing them to crawl or burrow.

**Hint**: Remember that muscle types in annelids are crucial for their movement.

2. **Role of Parapodia**:
- The second statement states that parapodia help in swimming, specifically in aquatic annelids. This is also true, as parapodia are extensions that assist in locomotion in water for species like polychaetes.

**Hint**: Think about the adaptations of annelids to their environments, especially aquatic ones.

3. **Excretion Mechanism**:
- The third statement discusses Malpighian tubules and their role in excretion. The video clarifies that this is incorrect. Annelids do not use Malpighian tubules for excretion; instead, they utilize nephridia for this function. Nephridia are responsible for excretion and osmoregulation in annelids.

**Hint**: Differentiate between excretory structures in various animal groups; Malpighian tubules are more common in arthropods.

4. **Neural System Structure**:
- The final statement describes the neural system of annelids, which consists of paired ganglia connected by lateral nerves to the dorsal and ventral nerve cords. This statement is accurate and reflects the organization of the nervous system in annelids.

**Hint**: Recall the basic structure of the nervous system in segmented animals.

### Conclusion:
The incorrect match regarding the characteristics of Annelida is the statement about Malpighian tubules being involved in excretion. Instead, nephridia are the correct structures responsible for excretion in annelids.

### Final Answer:
**The incorrect match is: "Malpighian tubules help in excretion."**
