Agarden aboard the international space station allows space scientists to research the growth of plants in space. this research is important because astronauts will need to grow their own food to survive long space journeys. what challenges would you expect scientists to face when growing plants in space? what challenges will the astronauts have with meeting their own energy needs? scientists are also evaluating plants for gene mutations that would them grow better in space environments. what traits could a plant have that would it grow better in space?

Well, In space, roots grow in every direction, and water and other essential plants foods float. so the scientists need to find a way to keep the plant directed in their root growth and to find a way to keep water circulating properly. the plants will tend to grow away form the light source in zero gravity. the scientists will have to maintain the amount of light and water the plants get. To be aware of microorganisms that may grow on the plants and what to do about them. they have to l ow the proper amount of fertilizer to use and the right type of plant to use. plant that are larger and with any roots grow better. Such as, lettuce, peas and radishes. larger plants, more water grow better.

This type of galaxy is an approximately ellipsoidal shape and a smooth, nearly featureless image. they are the largest single star systems, in the universe and are built by the collisions of many smaller galaxies.
