WebA plant laid on its side in the dark will send shoots upward when given enough time. Gravitropism ensures that roots grow into the soil and that shoots grow toward sunlight. Growth of the shoot apical tip upward is called negative gravitropism, whereas growth of the roots downward is called positive gravitropism. WebAuxin, any of a group of plant hormones that regulate growth, particularly by stimulating cell elongation in stems. ….
