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 which direction do plants roots grow?
The roots of most plants grow towards the pull of gravity.
In gravitropism which direction do the roots grow?
Downward
In gravitropism which direction do roots 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
What is a negative gravitropism?
A tropism in which the roots of plant grow downward, in the direction of gravity
