A student cuts a small piece from the stem of an adult plant and a small piece of muscle from an adult mouse.
She puts each piece in a dish of growth jelly containing all the nutrients and plant hormones the cells need.
Only the piece of plant stem grows into a whole new organism.
Which statement best explains this result?
Plant cells can differentiate, but animal cells cannot differentiate at any stage.
Plant cells divide by mitosis but animal cells do not.
Most cells in the adult mouse muscle have already differentiated and cannot become other types of cell.
Animal cells need oxygen but plant cells do not.
