Statement I: The acrosome is a cap-like structure located at the posterior end of the sperm nucleus.
Statement II: The acrosome contains enzymes such as hyaluronidase and zona lysin or acrosin which help in the process of sperm entry into the ovum.
Both statements are true and statement II is the correct explanation of statement I.
Both statements are true but statement II is not the correct explanation of statement I.
Statement I is true but statement II is false.
Statement I is false but statement II is true.
The acrosome is located at the anterior end of the sperm nucleus, not the posterior end.
The acrosome is a specialized structure present in the head of the sperm. It is a cap-like structure that covers the anterior part of the nucleus. It contains a variety of enzymes, including hyaluronidase and acrosin, which are involved in the process of fertilization.
Therefore, statement I is incorrect. Statement II, which states that the acrosome contains enzymes that help in the process of sperm entry into the ovum, is correct.
Option 4 is the correct answer.
