Which one of the following protists is not correctly linked to the type of movement it shows ?

Options

A. Amoeboids-pseudopodia
B. Ciliates-cilia
C. Zooflagellates-flagella
D. Sporozoa-flexing the pellicle

Explanation

To solve the question "Which one of the following protists is not correctly linked to the type of movement it shows?", we will analyze each option provided and determine if the movement type is accurately associated with the protist mentioned.

### Step-by-Step Solution:

1. **Option 1: Amoeboids - Pseudopodia**
- Amoeboids, such as Amoeba, move using pseudopodia. Pseudopodia are temporary, arm-like projections that extend from the cell body and are used for movement and feeding. This option is correctly linked.
- **Conclusion:** Correct association.

2. **Option 2: Ciliates - Cilia**
- Ciliates, like Paramecium, have numerous tiny hair-like structures called cilia that cover their surface. These cilia are used for swimming, crawling, and feeding. This option is also correctly linked.
- **Conclusion:** Correct association.

3. **Option 3: Zooflagellates - Flagella**
- Zooflagellates, such as Euglena, move using one or more flagella. Flagella are whip-like structures that propel the organism through liquid. This option is correctly linked as well.
- **Conclusion:** Correct association.

4. **Option 4: Sporozoa - Flexing the Pellicle**
- Sporozoa, such as Plasmodium, do not have cilia, flagella, or pseudopodia for movement. The pellicle is a flexible layer that helps maintain the shape of the organism but does not aid in locomotion. Instead, sporozoa exhibit gliding movement. Therefore, this option is not correctly linked.
- **Conclusion:** Incorrect association.

### Final Answer:
The protist that is not correctly linked to the type of movement it shows is **Sporozoa** (flexing the pellicle).
