How gravity effects plants' growth?

If we plant 2 same planting on space and earth with different gravity,
On earth, more water would be stayed on roots.
On space, there is no different on water's distribution.

Does anyone have any suggestions on how different gravity effects plants' growth?
Thanks in advance for any suggestions :>

Does anyone have any suggestions on how gravity effects calcium levels in plants' cells?

Thanks in advance for any suggestions :>


"In the Kibo module, the plants will be placed in both the micro gravity ISS environment and in a small centrifuge, that can simulate Earth’s gravity.

Results will show if the plants can sense changes in gravity, and adapt levels of calcium in their cells to compensate for it."

Do gravity make roots' growth better by increasing calcium concentration?
Thanks in advance for any suggestions :>

"In particular, scientists think particles in plant cells that store and process starch for energy - amyloplast - may form in the direction of gravitational pull.

By increasing calcium concentrations, the amyloplast can help the plant grow in a certain direction.

Without gravity, though, scientists will be keen to see whether the same components can still assemble to make the plant grow in a certain direction.

If the role of amyloplast is proven to be correct, it could mean that plants on Earth could be modified to make them more healthy.

And it could also help cultivate healthy plants for consumption on future deep space missions, or even other planets."
