    Is this your question?
    Hello Students! Several of you submitted questions to the Public Affairs Officer about your plants. Look for for your question in this string to see the answers.

    How come premature deaths of plants (ex.soybean) happen more often then wheat?
    If you go to "View Data" in the online data notebook and select the "Calamity Graph" you will notice that 6.9% of all soy seeds and 5.5% of all wheat seeds experience a premature death. This is a difference of about 1.4% There may be various reasons for this, but overall, it is not a significant difference between the two plants.

    Have you guys started the experiment in the space station?
    Yes, the actual wheat and soy were taken up to the space station last spring on STS-110 and STS-111. Astronaut Dan Bursch took care of the wheat and Astronaut Peggy Whitson took care of the soy. You can find more information in the Payload 003 Section of the website, http://www.space-explorers.com/internal/ol/3/

    why did you choose the Soybean and Wheat Plant for this experiment?
    This question was submitted by a student at Walker Middle School in Orlando, Florida. These particular seeds were chosen becuase Pioneer and Utah State University researched and developed the seeds over many generations to genetically select a fast growing, but not too large plant so it could grow on the space station.

    Why do you want to grow plants in the outer space and for what reason?
    This question was submitted by another student from Walker Middle School.The idea behind growing plants is space is to learn as much about food production in space as we can. Why do we care if we can grow food in space? Because it is necessary if we are ever to colonize another world, like the Moon, or if we are to take a very long trip to a far-away planet like Mars.

    since chlorophyll gives a plant the green pigment, why cant a plant be purple or red, etc
    This is a great question! Plants *can* be purple, red, etc! Chlorophyll is the strongest color producing chemical in a plant...but what happens to green leaves in autumn? They turn beautiful shades of colors becuase the tree has stopped producing chlorophyll as it prepares to drop its leaves and stop photosynthesizing for the winter season. Other plants such as hostas or japanese maples may naturally have colors such as purple and red.
