Solution and Explanation

Step 1: Overview of the Sperm Structure. - The human sperm is a microscopic, motile cell with three main parts: head, middle piece, and tail.
Step 2: Describe Each Part. - Head: Contains the nucleus with the genetic material (haploid DNA). It is covered by a cap-like structure called the acrosome, which contains enzymes to penetrate the egg during fertilization. - Middle Piece: Contains mitochondria that provide energy for the sperm's movement. - Tail (Flagellum): A long whip-like structure that enables the sperm to swim towards the egg.


Final Answer: The human sperm consists of a head (with genetic material and acrosome), middle piece (with mitochondria), and a tail (for motility).
