The roots of plants and trees grow into the ground for a number of reasons. Firstly it is to maintain stability so they don't collapse and secondly they grow to to find water and absorb the water that is in the ground.

∙ 11y agoIt is essential for roots to grow down so they can explore the soil and maximise their water uptake. But how they know that is a question that has fascinated scientists since Darwin. Now scientists led by The University of Nottingham have found the answer.
Gravity profoundly influences plant growth and development. But after years of academic research the interdisciplinary team from the UK, Germany, France, Belgium, Sweden and the US has finally identified how that process happens. Their results have been published in the leading academic journal Proceedings of the National Academy of Sciences of the United States of America(PNAS).
With funding from the Biotechnology and Biological Sciences Research Council (BBSRC), Malcolm Bennett, a Professor in plant science at The University of Nottingham and Biology Director of the Centre for Plant Integrative Biology, used newly developed technology to pinpoint what happens when plant roots decide to grow down and not up. He said: "This research really demonstrates the value of an interdisciplinary approach to plant science questions. By combining the skills of mathematical modellers with experimental biologists we have a new range of tools with which to investigate root growth.
HOPE IT WAS HELPFUL.

What causes roots to grow downward?
Gravitropism (also known as geotropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Wikipedia
Do the roots of a plant always go downward?
Plant roots grow whatever direction is necessary to acquire the largest quantity of water most easily. For example, a tree in the desert will grow roots very, very deep to get to the resources of water there. However, if you constantly water a tree, its roots will grow sideways just below the surface of the soil (which, by the way, can cause it to be unstable in high wind, and even blow over).
Why do a plants roots always grow downward and its shoots always grow upward?
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.
Why do sporangiophore grow vertically whereas rhizoids grow downward?
The sporangiophore grow vertically because it is positively phototrophic. The rhizoides being positively geotrophic grow downward.
What type of root system does grass have?
It has a Fibrous Root System. The roots grow downward, and split into many. A Tap Root (as the previous answer said) is just one root going downward.
In gravitropism which direction do the roots grow?
Downward
In gravitropism which direction do roots grow?
Downward
What causes roots to grow downward?

Why do roots grow downward?
Plant roots are capable of performing this trick by sensing gravity (geotropism or gravitropism). In space they grow in random directions.
Does roots grow in random directions when they are blocked from growing downward?
Apparently yes they do. Most plant roots grow to the sides..that is if they don't die.
How do roots know to grow downward?
Because they need to anchor down the plant.
Do roots grow in random when they are blocked from rowing downward?
When roots are blocked from going random they just stop growing.
Will palm tree roots damage your pool?
palm tree roots grow mostly downward so they are not likely to damage your pool
Do plants grow downwards?
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.
Do roots grow in random directions when they are blocked from growing downward?
The answer is yes because once blocked by something where else does the root have to go but everywhere! So yes, roots grow in random directions when blocked.
When a plants roots grow downward this is an example of?
a dandelion is a tap root which goes down ward in to the ground
What causes a tree to lean on the a hillside?
the roots grow in crooked and on an angle
