What happens to differentiation in plant cells?
The differentiation is not permanent. You can move a plant cell from one part of a plant to another. There it can dedifferentiate and become a completely different type of cell.
What is cloning of cells?
Producing identical offspring is know as cloning. In the right conditions a plant cell will become unspecialised and undergo mitosis many times. Each of these will roused more cells by mitosis. The new plants will be identical to the original parent.
