Reaching the Age of Adolescence
The table below shows the data on likely heights of boys and girls as they grow in age. Draw graphs showing height and age for both boys and girls on the same graph paper. What conclusions can be drawn from these graphs?
Solution: The graph shows the relation between the age and height of both boys and girls.
During puberty, there is a sudden spurge in height of both boys and girls. From the graph, we can see that during the age of 4-8 years, girls have less height as compared to boys. However, as soon as girls reaches the start of adolescent phase, i.e., 12- 13 years, their height shows a sudden increase and becomes more than boys. In later years, growth in both sexes becomes stable. Growth during puberty is controlled by various hormones which are the control of the pituitary gland.
