How To Use Geotropism In A Sentence

But atavistic, or vestigial, geotropism in Genesistrine -- or a million larvae start crawling, and a million little frogs start hopping -- knowing no more what it's all about than we do when we crawl to work in the morning and hop away at night. The Book of the Damned
The main stems of a plant show negative geotropism as they grow upwards.
They give the quintessence of laboratory experiments as to what are the effects of different energies such as light (heliotropism), electricity (galvanotropism), gravity (geotropism), etc., in their reaction and influence upon the movements and actions of living organisms. Manhood of Humanity.
It was shown that gaseous ethylene inhibits both growth and geotropism in plants, and ethylene is endogenously produced by fruits.
Once plant life invaded the land it was subject to the action of gravity, and geotropism ( "earth-turning" G), involving an automatic and adaptive response to gravity, was developed. The Human Brain

Geotropism occurs in two forms: positive geotropism to which the root responds by growing downward; and a negative geotropism, which causes the stem to grow upward.
Transversal geotropism is a direction of growth that is vertical to the shoot axis.
They give the quintessence of laboratory experiments as to what are the effects of different energies such as light (heliotropism), electricity (galvanotropism), gravity (geotropism), etc., in their reaction and influence upon the movements and actions of living organisms. Manhood of Humanity.
This is the best way to maximize grow space, minimize power consumption, and utilize geotropism to spread growth auxins throughout the plant.
Thus I am now observing something about geotropism, and I had no idea a few weeks ago that this would have been necessary. More Letters of Charles Darwin — Volume 2
They give the quintessence of laboratory experiments as to what are the effects of different energies such as light (heliotropism), electricity (galvanotropism), gravity (geotropism), etc., in their reaction and influence upon the movements and actions of living organisms. Manhood of Humanity.
To account for the positive geotropism of roots, some researchers have proposed that under the influence of gravity, starch grains within the cells of the root fall towards the bottom of the cell.
