Question

Given below is the diagram of a human sperm. Read the information below the diagram and fill in the blanks:

Hint:

The sperm consists of a head (with acrosome for fertilization), a middle piece (containing mitochondria for energy), and a tail for motility. All are essential for successful fertilization.

Answer 1

Step 1: Explanation of the sperm structure.
Human sperm are microscopic structures that carry genetic material. The sperm structure includes the head, middle piece, and tail, each with specialized functions.
Step 2: Fill the blanks.
(a) {Acrosome} is the cap-like organelle on the head of the sperm. It contains enzymes like {Hyaluronidase} that help dissolve the outer layer of the ovum to facilitate fertilization.
(b) The enzyme produced by the acrosome is {Hyaluronidase}, which dissolves the outer layer of the ovum during fertilization.
(c) The nucleus of the sperm has {23} chromosomes, which carry the genetic information required for the creation of a new individual.
(d) The middle piece of the sperm contains {Mitochondria} that provide the energy needed for the motility of the sperm, allowing it to swim towards the egg.
(e) {Semen} is a mixture of sperm and the fluids produced by the male accessory glands, which help nourish and protect the sperm during their journey to the egg.
