3. growth and development
adults don't always look like the bables of a species. all organisms begin their lives as single cells. over time,
these organisms grow and take on the characteristics of their species. growth results in an increase in the amount of
living material and the formation of new structures.
all organisms grow, and different parts of organisms may grow at different rates. organisms made up of only
one cell may change little during their lives, but they do grow. on the other hand, organisms made up of numerous
cells go through many changes during their lifetimes. think about some of the structural changes your body has
already undergone in your short life. all of the changes that take place during the life of an organism are known as
its development.
