Transpiration

Activity:

   Celery

• Fill a plastic cup about 1/3 full of water.

• Place a few drops of food coloring in the water and use a Popsicle stick to stir it.

• Cut the two ends of the celery stalk to remove the scar tissue.
• Place the celery stalk so that one end is immersed in the water and the other side is in the air. 

• Set the cup with celery in a safe place overnight.
• Look at the vascular bundles in the celery the next day and see if you notice a change.

The next day......

Prediction:
I think that the whole celery would be a fade of red.

Explanation: 
 I guess I was wrong, the celery has turned red though the veins of the celery, the function is called xylem. I had to cut the end of the celery to see the change.




   Carnation

• Fill the designated container about 1/2 full of water.

• Place a few drops of food coloring in the water and use a Popsicle stick to stir it 

• Cut the stem at an angle such that the carnation will stand up in the container overnight 
• Place the carnation in the water.

• Set the carnation and the container in a safe place overnight
• Predict what might happen to the carnation.
• Observe the carnation the next day and see if you notice a change.

The next day....

  Prediction:
  Since I've seen this done before I know what happens I just didn't know the scientific way to explain it so now I know that the food colored water gets pulled up and enters the roots of the plant up through the xylem. 

Observations:

The next day there was a fade of color change, so I left it for another day. The day after I seen a little bit of change but not much because I think I would have seen a bigger difference if i added more food coloring.  

Explanation:

• When the plant needed water it didn't have just water it had the food coloring so once it traveled through xylem the petals started to change color to the chosen color could be any color but I had red so it changed red.
