The relationship between the celery, water temperature, and capillary action in the celery is the transpiration, adhesion, cohesion, osmosis, and respiration processes. Respiration is related to this experiment because when the water evaporates from the leaves(transpiration), it pulls water from the tubes of the celery, called xylems, and causes the water to rise, as well as the capillary action causes the rising. Water molecules are attached to each other through cohesion, so they don’t want to “let go” of the other water molecules they/it is attached to. We saw evidence of this when we cut down the celery in small slivers until we saw the dye that had risen up the tube. The hot water traveling up the celery’s xylems was unsuccessful because …show more content…

That trial run was unsuccessful. The colored water for each the hot, room temp, and cold water did not rise above the waterline in the celery. The water levels were at four inches, and the water in the celery xylems did not rise much above four inches during the alotted 6 hour time period. When the trial was run with 8 inch stalks of celery, with leaves, it was much more successful. The cold water rose 20.32 centimeters total, over 3 hours. The room temperature water rose 7.62 centimeters total over the 3 hour time period. The hot water rose 17.78 centimeters total, over the 3 hours. The water in the stalks without leaves did not rise, and was therefore unsuccessful, while the water in the stalks WITH leaves rose several more centimeters over a shorter time span, showing that respiration is linked in to the …show more content…

Capillary action uses both adhesion(water “holding” on to a surface) and cohesion (water holding on to water). The adhesion lets the water gradually grab onto the surface of the xylems and “pull” itself up the stalk of the celery, or any tube small enough for this. Cohesion lets the water molecule(s) hold onto other water molecule(s) and pull eachother up while they are using adhesion at the same time to climb up the xylem walls. Transpiration relates to both adhesion and cohesion because the water is able to connect to eachother while being pulled up by the water going out of the leaves. This relates to our experiment because when the first trial was run with the stalks without leaves, the water went up a very small amount, but did not go up nearly as much as when the leaves were left on the celery stalks. Cohesion and adhesion were being used through capillary action during the first trial, but the second tria, transpiration was combined to
