Question
The diagram shows a human sperm. Inside the tail of the sperm is a filament mechanism that causes the side to side movement of the tail, which moves the sperm.8.

Solution
(a) The mitochondria are often referred to as the "powerhouses" of the cell because they are responsible for producing adenosine triphosphate (ATP), the cell's main source of energy. This energy is crucial for the sperm to move and propel itself towards the egg for fertilization. The mitochondria are arranged around the filament near the tail of the sperm to provide energy directly to the tail. This arrangement allows for efficient energy transfer, enabling the tail to move rapidly and propel the sperm forward.
(b) The nucleus of a sperm cell contains half of the genetic material necessary for the creation of a new organism. This genetic material combines with the genetic material from the egg to form a complete set of chromosomes. The characteristics of the offspring, such as physical traits, potential health risks, and even some aspects of personality, are determined by this combination of genetic material. Therefore, the nucleus of the sperm plays a significant role in determining the characteristics of the offspring.
