"The features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity," said study co-author Anna-Lisa Paul. "There's really no impediment to growing plants in microgravity, such as on a long-term mission to Mars, or in reduced-gravity environments such as in specialized greenhouses on Mars or the moon."

Plants able to grow without gravity

Scientists have determined that it is possible to grow plants in space despite the lack of gravity.
Experiments on the International Space Station have demonstrated that plants can thrive in space and grow in much the same way as they do on Earth. The discovery is important because it means that astronauts in the future will be able to grow their food during long space voyages such as on a trip to Mars."The features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity," said study co-author Anna-Lisa Paul. "There's really no impediment to growing plants in microgravity, such as on a long-term mission to Mars, or in reduced-gravity environments such as in specialized greenhouses on Mars or the moon."
Since the flowers were orbiting some 220 miles (350 kilometers) above the Earth at the time, the NASA-funded experiment suggests that plants still retain an earthy instinct when they don't have gravity as a guide.
