The Plant Cell wall
... Plants can not move. The form of the plant body is controlled by the way plant cells expand and alter in shape. The direction in which plant cells divide, and thus the direction in which the plant itself grows, is ultimately governed by the plant cell wall. Many factors control the formation of new ...
