"Geototropism" is not a recognized botanical term. You may be thinking of geotropism, which is the growth response of a plant to gravity.

Geotropism is a vital aspect of plant development that ensures proper orientation and growth:

* Positive geotropism: Roots grow downwards towards the pull of gravity, anchoring the plant and accessing water and nutrients.

* Negative geotropism: Shoots grow upwards against gravity, reaching for sunlight for photosynthesis.
