* Body cells (also called somatic cells) are the basic units of life that make up all the tissues and organs of a living organism. Examples include skin cells, muscle cells, nerve cells, etc.
* Nucleus is a membrane-bound organelle found inside most body cells. It contains the cell's genetic material (DNA) and controls the cell's activities.
Think of it like this:
* Body cells are like houses.
* Nucleus is like the control center of the house (the living room where the family gathers and makes decisions).
So, every house (body cell) has a control center (nucleus), but the control center is not the same as the whole house.
