as you prabably already know, plants feed souly off of soil, (dirt), and the roots will always be trying to gain more and more nutritions from the dirt, and will keep trying to go deeper.
(THAT ABOVE IS NOT POSTED BY ME)
*plants are gravitrophic meaning that the roots will always grow towards gravity and to of course absorb the nutrients, but there are some plants that do grow outside of of the soil like in pots and they still grow downward.
the stimulus in this case is gravity .
shoots grow up,away from gravity.
roots grow down,towards gravity.again auxin control this growth.
if a plant is put its side the auxin builds up on the lower side of the shoot and the root.
No, plants do not always grow downward. Plant roots always grow downward due to positive gravitropism or positive geotropism. Plant shoots always grow upwards due to negative gravitropism or negative geotropism.
You'll probably want to avoid material which would need much upkeep, and go with metals or plastic. This means that you should get a metal desk, and probably go with a plastic chair with easily cleanable cushion.
They usually grow upwards, but if the light source is further away from the plants, they tend to lean towards the source.
Plants do not grow in the direction of gravity. Though a plant's roots travel downward, the plant grows in the direction of the most sunlight, because sunlight provides the plant's energy.
Not always, downward growth takes place mostly in hanging plants such as Portulacaria etc.
Plants grow upward towards the light, their roots grow downwards
Elongation of the meristematic tissue
When you inhale, your diaphragm contracts and moves downward, and when you exhale, your diaphragm relaxes and moves upward.
Water and minerals are transported within the plant by the Xylem vessels (mainly in an upward direction); these are part of the vascular system which also includes Phloem vessels. Phloem transports the products of photosynthesis within the plant (mainly in a downward direction)
Plantar abduction. Movement inward is adduction. Upward movement of the foot is called dorsiflexion. Downward movement of the foot is called plantar flexion.
The stem of terrestrial plants are strong to support themselves as they grow upward. Without this physical characteristic, they would simply fall over after growing a few inches.

The upward and the downward bias refers to the overestimation or overstatement by a statistical measure of a given event.

You can change your notes on the tuba by moving your lips upward or downward. Upward is lower, downward is slightly higher than upward and just stright means high.
Upward, downward and lateral
No, gravity is a downward force.
