3. In 2010, NASA sent Arabidopsis seeds to the International Space station and grew them under zero gravity conditions. To their surprise, the plants germinated and developed shoot and root systems growing in opposite directions and the root showed patterns of normal root growth behavior. What might this suggest about gravity's role in plant seed germination and development and how do you think plants were able to diversify shoot and root systems without gravity?
