Question
In the absence of acrosome the sperm cannot ________________
1 mark
- a) Penetrate egg
- b) Get energy
- c) Get food
- d) Swim
Solution
The acrosome is a specialized structure located at the tip of the sperm cell, and it plays a crucial role in the fertilization process. It contains hydrolytic enzymes that are essential for the sperm to penetrate the outer layers of the egg, specifically the zona pellucida. When the sperm reaches the egg, the acrosome reaction occurs, releasing these enzymes which help to digest the protective layers surrounding the egg, thus allowing the sperm to access the egg's plasma membrane and initiate fertilization.
Given this function, if the sperm lacks an acrosome, it cannot effectively penetrate the egg. Therefore, the correct answer to the question is:
Final Answer: a) Penetrate egg
