The functions of the individual indepedent cells happen to different according to their morphology and anatomy. These variety in structure makes these independent individual cell function is a more simpler way than interdependent cells like of organisms. However, these interdependent cells doesn't mean they rely on process of other cells but instead they work together which readily forms the hierachy to tissues. etc and etc.
The structures of the
body or the set organ relates to its function by the cell that form the
organ. In a cellular level, cells makes up the tissues which make up
the organ then the organ system. Focusing in organs, these organs
functions accordingly as what they're supposed to do and was formed to
such degree to ensure its optimum performance for example, the skin is
made up of epithelial tissues which has seven layers which serves as a
protective layer of the body. Another is the brain, the brain is made up
of many nerve tissues and cells that allows it to do its responsibility
or acted function, since nerve cells are the cells responsible for
functions like sensitivity, reaction, emotion, memory, sensation &
perception and etc the brain is made from brain cells, itself.
