Well speaking scientifically the radish plant would probably die because of its reaction to the saltwater.Try out the experiment.
The higher the amount of salt in the soil outside of the plant cells causes water to move outside of the plant cells to try and equalize the all the concentration. Root cells die and, if bad enough, the plant will die. The damage that the salt water gives, makes the plant get a burnt look,often on the leaf edges first.
== The reaction that photosynthesis causes is that you get food with out watering the plant although it might take longer. The plant needs food to live or else it can die if it doesn't have sunlight or water it can cause the plant to dry out and die. == Photosynthesis is the process by which a plant converts sunlight, carbon dioxide, and water into food that it can use to grow.
