When one examines the roots of a plant, one sees a tangled mess of tendrils. It is well known that plant growth patterns are influenced by a variety of stimuli, gravity being one amongst many. On Earth plant roots exhibit characteristic behaviors called waving and skewing, which were thought to be gravitydependent events.

Plant Life: Tropisms

Tropisms are the means by which plants grow toward or away from environmental stimuli such as light, gravity, objects to climb, moisture in soil, or the position of the sun. Although plants appear not to move, they have evolved adaptations to allow movement in response to various environmental stimuli; such mechanisms are called tropisms.

The Wonderwheel: A Study of Gravity's Effects on Plant Growth Purpose: This is an experiment to study gravitational effects on plants. What are the effects of gravity on a plant when it is not grown in the natural position? Will the plant grow at all? If so, what changes in the plant's structure may occur?

In higher plants the gravity susceptors, or statoliths, are believed to be dense amyloplasts that sediment in specialized cells, or statocytes (Haberlandt, 1900; Nemec, 1900). In shoots and grass pulvini, amyloplastcontaining statocytes are located in the starch .

Plant Responses to Gravity. Whether or not they germinate in the light or in total darkness, shoots usually sprout up from the ground, and roots grow downward into the ground. A plant laid on its side in the dark will send shoots upward when given enough time. Gravitropism ensures that roots grow into the soil and that shoots grow toward sunlight.

Dec 07, 2012· On Earth plant roots exhibit characteristic behaviors called 'waving' and 'skewing', which were thought to be gravitydependent events. However, Arabidopsis plants grown on the International Space Station (ISS) have demonstrated this theory wrong, according to a new study: root 'waving'...

Plants have utilized gravity as the most stable and reliable signal for their survival over the course of evolution. Microgravity is one of the most significant features of orbital flight in space. Thus, we predict that plant growth and morphogenesis will be greatly modified under space conditions.

The water in plants can exist at such low water potentials due to the cohesive forces of water molecules. The chemical structure of water molecules is such that they cohere very strongly. By the cohesiontension theory, when sunlight strikes a leaf, the resultant evaporation first causes a drop in leaf water potential.
