Biology Question on Reproductive Health – Problems And Strategies
Which part of the sperm help in its entry into the cytoplasm of the ovum ?
A
Plasma membrane
B
Nucleus
C
Neck
D
Acrosome
Answer
Acrosome
Explanation
Solution
The correct option is(D): Acrosome.
The part of the sperm that helps in its entry into the cytoplasm of the ovum is the "Acrosome."
The acrosome is a specialized structure located at the tip of the sperm's head. It contains enzymes that are released upon contact with the zona pellucida, which is the outer protective layer of the ovum. These enzymes help in the process of fertilization by breaking down the zona pellucida, allowing the sperm to penetrate and enter the cytoplasm of the ovum.
Therefore, the acrosome plays a crucial role in facilitating the entry of the sperm into the ovum.
