- The period of life when the body undergoes changes leading to reproductive maturity is called "adolescence."

- Adolescence is a transitional stage of development between childhood and adulthood.

- It generally begins with the onset of puberty and lasts until adulthood is reached. During this phase, individuals undergo physical, cognitive, emotional, and social changes as they mature and prepare for adulthood.

- Physical changes during adolescence are primarily associated with puberty, including the development of secondary sexual characteristics such as the growth of body hair, changes in voice pitch, and the development of breasts in females and facial hair in males.

- Cognitive development during adolescence involves the maturation of thinking abilities, problem-solving skills, and decision-making processes. 

- Emotionally, adolescents may experience mood swings and heightened sensitivity due to hormonal changes and the challenges of coping with their changing bodies and new social situations.
