Explanation:

• Cortical reaction: The reaction that takes place when the sperm has successfully penetrated an egg in order to prevent polyspermy is known as cortical reaction.
• In this reaction the secretory vesicles are cortical granules.
• It prevents polyspermy by establishing a permanent barrier to additional sperm entry.

• Acrosome reaction: The reaction in which the sperm reaches an egg and allows the sperm to break through the surrounding jelly coat is known as acrosome reaction.
• In this reaction, the secretory vesicles is an acrosome.
• This reaction allows the sperm by exocytotic release of acrosomal enzymes to penetrate the zona pellucida of the egg.
