Plants in Gel Revisited




If you recall from earlier posts we discovered that seeds planted in diaper gel alone do not grow. We also turned the seeds that sprouted upside down to examine gravitropism; unfortunately the experiment didn't work, the roots dried out because I didn't cover them. Then I planted some beans that sprouted in the gel to see if they would grow. If you look closely at the pictures you can see they did not do well, the roots started to mold. The plants that grew in the cotton and paper towels are doing very well, however.
