Quizplus · Accepted Answer

The statement that is False is D) Plant cells differentiate because the cytoskeleton determines which genes will be turned "on" and "off." While the cytoskeleton plays a role in determining cell shape, it does not directly determine gene expression or differentiation. Differentiation in plant cells is directed by signals from neighboring cells and by the plant's developmental program.
