Geotropisms Geotrophic Grow Shoots Negatively Light Roots Positively

Shoots exhibit negative geotropism by growing upwards, away from gravity, while roots demonstrate positive geotropism by growing downwards into the soil. Experiments with clinostats, which eliminate directional gravity, show straight growth in shoots.

Shoots exhibit negative geotropism (growing upwards against gravity), while roots show positive geotropism (growing downwards with gravity). Experiments using a clinostat, which rotates plants evenly, demonstrate that without a consistent gravitational stimulus, shoots grow straight.
