Question
**Understanding Sperm Motility in Fertility Tests** Sperm motility is a vital feature assessed in any fertility test. The movement of human sperm is facilitated by the presence of specific structures. Consider the following multiple-choice options to identify which structure contributes to sperm motility: - ○ cilia - ○ acrosome - ○ flagellum - ○ actin tubule - ○ pseudopodia **Explanation:** The correct answer is **"flagellum."** The flagellum is a whip-like structure that enables sperm to swim and move effectively. It is crucial for the motility necessary for successful fertilization. Other options explained: - **Cilia**: Hair-like structures that typically help in movement but are not responsible for sperm motility. - **Acrosome**: A cap-like structure in sperm, containing enzymes that help penetrate the egg but do not aid in motility. - **Actin tubule**: Part of the cytoskeleton, involved in cell shape and movement, but not the primary factor in sperm motility. - **Pseudopodia**: Extensions of the cell body found in some cells like amoebas, not related to sperm movement.
