As you complete the experiment, record your data. If using the video, you may want to stop it when the experiment displays the 15 minute mark, the 30 minute mark, and when the cross-section is shown under the microscope. Submit your data and answers to the following questions: 1)After the first 15 minutes, describe what is happening to the leaves on the celery stalk.
2)Compare the color of the leaves from 15 minutes to 30 minutes. Give a reason why the leaves look different.
3)Looking at the cross-section, describe what you see. Can you identify the transport bundles of xylem and phloem? What color are they?
4)How does this lab prove vascular tissues carry water and minerals up the stem?
5)Predict what would happen if you repeated this experiment, but instead of using red food coloring, you use blue.

Where does all the water go? according to the environmental protection agency (epa), in a typical wetland environment, 39% of the water is outflow; 46% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem (reference: united states environmental protection agency case studies report 832-r-93-005). chloride compounds as residuals from residential areas are a problem for wetlands. suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found: outflow, 60.4; seepage, 73.7; remaining due to evaporation, 26.4; in the water volume, 46.8. (a) compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (round your answer to one decimal place.) mg/l (b) suppose the epa has established an average chlorine compound concentration target of no more than 58 mg/l. does this wetlands system meet the target standard for chlorine compound concentration? yes. the average chlorine compound concentration (mg/l) is too high. yes. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is too high.
