Question

Your essay should answer the following:

Describe the cross-section of the thin celery slice. What does it look like?

Try to identify the "stringy" transport bundles of xylem and phloem. What color are they?

How does this prove they carry water and minerals up the stem?

Look carefully at the leaves of the celery. What color are they?

Explain the change in color of the leaves that you saw.

Answer 1

It looks like its been draining/drinking on smiting for some time and if you look closely you'd see the color of dye in it xylene and phloem

they are the color of dye in this case red

as you can see in this case the celery was left for 30 min. at first you could see that it was going up a bit, then after 24 hrs it went to the leaves and as we broke it in half it was shown that that the f

phloem and xylem had some stains of red dye

they are red

well as water passes through the phloem and xylem the plant drinks it up and water doesn't have color so, as this dyed water passes it shows where it goes from the stem to the leaf

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
