The main difference between cancer cells and normal tissue stem cells is that cancer cells are abnormal and present mutations.
Plant and animal cells are different, too. The main difference between plant and animal cells is that plant cells have a cell wall on the outer layer, whereas animal cells only have a cell membrane. The cell wall is a protective layer outside the cell membrane that also provides support for the cell's structure.
