Arboretum Field Trip Remote (1) (1)

Plant Adaptation to Climate (Replacement for CSU-Fullerton Arboretum Field Trip) Assignment 1. Read the Introduction section of Arboretum Lab provided by your instructor. 2. Based on your reading, summarize the following climates: Temperate Zone_____________________________________________________________ Tropical Zone________________________________________________________________ Arid Zone___________________________________________________________________ 3. Click on the links below to view photos of plant communities from the three different climate zones: a. https://www.flickr.com/photos/184125683@N05/albums/72157713824454436 b. https://www.flickr.com/photos/184125683@N05/albums/72157713824421831 c. https://www.flickr.com/photos/184125683@N05/albums/72157713826062472 4. Based on your observations of Temperate, Tropical, and Arid climates and plant communities, complete the following hypotheses: ● I hypothesize that the ____________________ climate zone will have the longest average leaf length and the ____________________ climate zone will have the shortest. ● I hypothesize that the ____________________ climate zone will have the widest leaves and the ____________________ climate zone will have the narrowest. ● I hypothesize that the ____________________ climate zone will have the darkest leaves and the ____________________ climate zone will have the lightest. ● I hypothesize that the ____________________ climate zone will have the tallest average plant height and the ____________________ climate zone will have the shortest. 5. Use the information in Tables A-C (below) to test your hypotheses. Record your data in Tables 1-3 from the Arboretum Lab provided by your instructor. Make sure all measurements are recorded using metric system units (i.e. meters and centimeters). You may have to convert some of the measurements from English system units to metric system (2.54 cm = 1 in.; 1 m = 3.28 ft.). 6. Summarize your results. How does leaf length, shape, and color compare in the three climate zones? How does the average plant height compare?

How could being tall benefit plants in wetter climates? ______________________________ ___________________________________________________________________________ 13. What kind of environment would favor plants with broad leaves? _____________________ ___________________________________________________________________________ 14. How could leaf color influence a plant’s ability to capture sunlight? ____________________ ___________________________________________________________________________ 15. How could leaf color influence a plant” ability to conserve water? _____________________ ___________________________________________________________________________
