Well, roots will always grow down due to geotropism. It is caused by the statocytes in the root cap. They sense the force of gravity and grow down according to it. But if the root does not have a root cap, then the plant will not necesarily grow down. And if the seed is layed on a flat place like a counter, then the roots will grow any which-way. I did an experiment on this for the science fair. I found it at: http://www.sciencebuddies.org/science-fair-projects/project_ideas/PlantBio_p034.shtml
Plants grow from the roots and seeds germinate in the roots as well.
Struck roots is the past of strike roots. This means the seeds started to grow, they started to grow roots
No, not at all.
The roots of most plants grow towards the pull of gravity.
Downward
seeds should first form roots then they grow stems and then the grow leaves and after that they sprout shoots then they grow bigger then they become a plant.
Outwards.
gravatropism
It knows whats up, when it finds "up" it will change the roots going up into the bottom stem. All the Roots below do not change, but gro slightly faster.
Downward
toward the sun light..................:)
Plants propagating from seeds get their root from the embryo itself. Those developing by vegetative reproduction get roots from the pericycle of the stem.
