Vedclass · Answer

(A) Geotropism (or gravitropism) is the growth movement of plants in response to gravity. While gravity is the primary stimulus,several internal and external factors can modify this response. Internal factors include the physiological state of the root and shoot apices,which are the sites of perception and response. External environmental factors such as temperature,light,and the concentration of atmospheric carbon dioxide $(CO_2)$ significantly influence the growth rate and the directionality of the geotropic response in plant organs.
