Plants Grow Without Gravity

Researchers sent plants to the ISS in 2010 to study how plant roots developed in a weightless environment.

The scientists found that their plants didn't need gravity. The research team thinks this ability is related to a plant's inherent ability to orient itself as it grows. Seeds germinated on the International Space Station sprouted roots that behaved like they would on earth - growing away from the seed to seek nutrients and water in exactly the same pattern observed with gravity.

The study revealed that features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity.

The finding boosts the prospect of cultivating food plants in space.

-- The study findings appear in the latest issue of the journal BMC Plant Biology
