Question
**Title: Structure of a Mature Sperm (Spermatozoa)** --- **Major Parts of a Mature Sperm:** 1. **Head:** - **Acrosome**: A cap-like structure that covers the anterior part of the sperm head. It contains enzymes essential for penetrating the outer layers of the egg during fertilization. - **Nucleus**: Located within the head, it houses the genetic material (DNA) necessary for reproduction. 2. **Midpiece:** - **Mitochondria**: These are arranged in a spiral around the beginning section of the tail. They provide the energy required for the sperm's motility. 3. **Tail:** - **Microtubules**: These form the axial filament that constitutes the structure of the tail. The tail, which functions as a flagellum, is essential for the propulsion and mobility of the sperm. --- **Diagram Explanation:** The diagram depicts a simplified sketch of a mature sperm cell, highlighting its major components: the head, midpiece, and tail. Each part is labeled clearly to indicate its function and contribution to the overall motility and functionality of the spermatozoa. --- **Table for Part Description:** | Part | Description | |-------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Head | Contains the acrosome and nucleus; the acrosome facilitates egg penetration, while the nucleus carries genetic information. | | Midpiece | Equipped with mitochondria that generate the energy needed for movement. | | Tail | Comprised of microtubules that form a flagellum; critically important for the sperm’s propulsion and ability to reach the egg. | ---
