The advantages of a plant with roots that grow down are that it helps to stabilize the plant and to hold it in place. It also allows the plant to find water, which is not always close to the surface.
It can collect more nutrients in the soil
most plant roots grow down, not up!
a dandelion is a tap root which goes down ward in to the ground
No, not at all.
They cant move they have no muscles to do that. All that the roots can do is grow.
Plants roots grow in cracks in rocks. This causes a rock to break apart. Animals dig in the ground and while digging, it breaks down rock gradually.
most plant roots grow down, not up!
Yes they do grow down, they can also create 'suckers' that are self rooting side plants
Not all plants have roots (eg phytoplankton) and while some plants do grow form their roots (eg grasses), most plants do not grow from their roots but from their apical growing tip.
The roots of most plants grow towards the pull of gravity.
Some plants grow up and down, the directions being determined by gravity. (stem up, roots down)
No. Plants are designed for the roots to grow in the direction of gravity and the leaves to grow against gravity. A plant grown upside down will adapt by curving its stem upwards again.
The water won't reach the roots.
You can try but the plant will try to grow upwards. All plants grow up and their roots grow down. This is coded in their DNA.
The roots of a plant will always grow down. This is to help it find water. The stem grows upwards to find light.

Ginseng
Plants grow from the roots and seeds germinate in the roots as well.
