science project: carrots

I did a science project for taproots, it told me in my science book to use carrots( since carrots are taproots). It said to cut off the tips off the carrots, then put one of them in the fridge, and the other in a cup of water with blue food coloring on a sunny windowsill or in my light hut. Then it said to check them in 24 hours but we went on a trip, so we checked when we came back. The carrot in the fridge was shriveled up and the one in the cup was shriveled on the tip and still orange, but the bottom of it in the water was blue and still fresh. We then cut the blue tip open and saw this

The blue food coloring was in the veins because it sucked in the water all the way to the tip. I learned that carrots need to have moisture around them or be in the ground to survive
