The Form of a Plant Body Is Mainly Determined by the Planes

The form of a plant body is mainly determined by the planes in which cells divide and by controlled changes in cell shapes.Which of these is not part of these developmental patterns?

A) Growth-regulating hormones and other factors influence the orientation of bundles of microtubules in the interior of the plasma membrane during cell division and cell expansion.
B) Transport vesicles respond to gravity.
C) Microtubules guide the orientation of cellulose deposition during the formation of new cell walls.
D) The orientation of cellulose fibers in the cell wall determines the cell's final shape.
E) Turgor pressure helps the cells expand in size after cell division.
