A snail moves with the help of the shell.

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question states that a snail moves with the help of its shell. We need to evaluate this statement.

2. **Identifying the Role of the Shell**: The shell of a snail is an exoskeleton made of calcium carbonate. Its primary function is to provide protection to the snail, not to aid in movement.

3. **Locomotion in Snails**: The actual movement or locomotion in snails occurs through a muscular structure known as the muscular foot. This foot is responsible for the snail's movement.

4. **Mechanism of Movement**: The movement of the snail involves the contraction and relaxation of muscles in the muscular foot. When the muscles contract, they push the body forward, allowing the snail to move.

5. **Conclusion**: Since the movement of the snail is primarily due to the muscular foot and not the shell, the statement "A snail moves with the help of the shell" is false.

**Final Answer**: The statement is false; snails move with the help of their muscular foot, not their shell.
