Explanation: Root is underground and non-green. It * obtains food from green part of the plant, mainly leaves which carry on photosynthesis . 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.
