Question

multiple choice question
the long projections shown here on sperm cells that enable cellular movement are called
______

• flagella
• cilia
• microvilli

Explanation:

To solve this, we recall the structures for cell movement:

• Flagella are long, whip - like structures that help in cell movement, and sperm cells use flagella (the long tail - like structure) for movement.
• Cilia are shorter and more numerous, and are not the structure of sperm for movement.
• Microvilli are for increasing surface area, not for movement.

So the correct structure for sperm's movement is flagella.

Answer:

A. flagella
