an orienting response to gravity
Plants' response to gravity: roots grow downward, showing positive geotropism, while shoots grow upward in a negative response. PICTURE
The influence of gravity on the direction of growth of plant organs; positive where growth is towards the center of the gravity of the earth, negative when away from it. ( BCFT). Cf. Heliotropism.
The growth of a plant in response to gravity.
a turning or growth movement by a plant in response to gravity. Plant parts that grow downward, such as the roots, would be positive geotropism. A negative geotropism would be the stems growing upward
Geotropism is a plant's reaction to gravity in which the roots go towards the pull of gravity, and the shoots go in the opposite direction.
