Which of the following best describes how plants exhibit movement due to growth?
A stem bending toward a light source
Growth movements (tropisms) occur when one side of an organ grows faster than the other in response to a stimulus.
In phototropism, auxin collects on the shaded side of the stem, cells there elongate more, and the stem bends toward light.
A Mimosa leaf closing and a Venus flytrap snapping shut are quick movements caused by changes in water pressure (turgor), not growth; water absorption by roots is not a movement.
Hence, a stem bending toward a light source is a movement due to growth.
