Yeah, I don't remember the technical term for it, it was like geo-something growth. The plant always grows against gravity because going opposite gravity means that it will go out of the ground and will find light and air and so on, which it needs for photosynthesis. Try looking at wikipedia for more info on this.

(1) The limbs would have to be strong enough to grow upward to counter the effects of gravity. If the limbs carry fruit, they must sustain that added weight as well. With ivy and other such plants, if there are no poles to brace the vines, these drag or fall to the ground instead of climbing upward, due to gravity. Also, young trees are often braced so that they grow straight while the trunk is still developing.
(2) Water that must travel up the plant is affected by gravity.
Look at celery stalks compared to what a tree must be able to carry up from the ground to feed all its limbs and branches.
Redwood trees that are 300 feet tall must carry water that far, which is about the length of a football field.
(3) If you hang a tire or swing on a tree, this added weight effects how much the limbs are pulled down and start to grow that way.

As vegetation develop taller they must have more potent aid buildings to counteract the outcome of gravity. That is why bushes are composed of woody fabric. Since wooden takes time to make and style right into a structurally powerful fabric, bushes are customarily lengthy lived perennials as a substitute of very speedy developing annuals. Plants corresponding to annual vines which might be tall and speedy developing,quite often develop on different vegetation to counteract the consequences of gravity, on the grounds that their possess stems are not able to aid their possess mass. Non-woody vegetation as they develop taller additionally have got to make investments assets into thicker and more potent stems to maintain the vegetation developing upright. Gravity may be some of the stipulations that results phone measurement.

Roots grow to gravity (gravotropic). Stems grow to light (phototropic). Some stems droop only as a side effect of being too weak.

the auxin (a hormone) in the shoot makes the shoot grow upwards against gravity, which is useful if the shoot is for some reason horizontal.
