Answer 1

can you add a picture of the celery slice and i will help but i cant explain if i cant see the celery sorry

Answer 2

1) The stringy transport of xylem and phloem becomes the color of whatever the food coloring color is. 

2) This proves they carry water and minerals up the stem, because if the food coloring does not effect the rest of the stem, it will stay in that same place.

3) you will have to answer this base on your observation
