Explanation:
The correct answer is option 'C' - Puberty.
Puberty:
Puberty is a stage in human development when a child's body undergoes several physical and physiological changes to become capable of reproduction. It is the phase during which boys and girls reach sexual maturity and are capable of producing gametes (sex cells) - sperm in boys and eggs in girls.
Key Points:
1. Puberty is a natural process that occurs in every individual during adolescence.
2. It is triggered by hormones secreted by the endocrine glands, primarily the pituitary gland.
3. These hormones stimulate the development of the reproductive organs and the production of gametes.
4. In boys, puberty usually begins between the ages of 12 and 16 years, while in girls, it typically starts between the ages of 10 and 14 years.
5. The onset of puberty can vary among individuals and may be influenced by factors such as genetics, nutrition, and overall health.
6. During puberty, secondary sexual characteristics also develop, such as the growth of facial and body hair in boys and the development of breasts in girls.
7. Puberty marks the transition from childhood to adulthood and is accompanied by emotional and psychological changes as well.
Conclusion:
Puberty is the stage at which boys and girls start producing gametes. It is a natural process that occurs during adolescence and is characterized by physical, physiological, and emotional changes. Understanding the concept of puberty is important for understanding the reproductive system and the overall development of individuals during their teenage years.
