Shoots of plant show upward movement and it can be designated to be

Plant tropisms are directional growth movements in response to external stimuli. The upward movement of plant shoots is primarily a response to gravity and light. While shoots are positively phototropic (growing toward light), they are designated as negatively geotropic (or gravitropic) because they grow upwards, away from the earth's gravitational pull [1]. Conversely, roots exhibit positive geotropism as they grow downward in the direction of gravity [1]. This differential growth is often regulated by the hormone auxin, which redistributes in response to the gravitational vector. Since the question specifically asks for the designation of the upward movement relative to the options provided, 'negatively geotropic' is the accurate scientific term for growth against gravity. Other options like positive hydrotropism or chemotropism describe growth toward water or chemicals, which typically characterizes root or pollen tube behavior rather than general upward shoot movement [1].
