Their own food supply. this is nothing new. astronauts have been growing crops in space for the past a0 years. but there s still an awful lot that scientists are trying to learn about space farming. we have things like radiation that we have to deal with. we also have issues with microgravity. plants have learned how to detect gravity with their roots and gravity sensing organelles in the plants, and so they know how to use these cues. and without these cues, they have to re adapt to this environment. so, without gravity, the next cue that they use is light. so how to go up and down, how to orient themselves is based on light now, cos they don t have gravity. water behaves very differently in microgravity. it has a high surface tension, so it likes to cling. and when the water clings to the roots, it prevents the roots from breathing. and so the plants can experience things like drought stress. they mayjust look green to you and me, but plants
