How the cells and tissues of brain organs work together to allow the organ to do its job

Cells are the smallest structural and functional unit of the Human body. When a group of specialized cells perform a single job they form a TISSUE. When a group of tissue carry out a particular function in the body they form the ORGANS.

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.
