5Stem: Function A. Transportation – transport water and nutrients. Xylem - transports water and nutrients from roots to leaves (upwards)Phloem - conducts products of photosynthesis throughout the plantB. Storage – store water and nutrientsC. Support – leaves
7Leaves: Function Photosynthesis: Leaves use light energy, carbon dioxide and water to make carbohydrates.B. Gas & Water Exchange:Plants have stomata that open or close for gas and water exchange with the environment.Stomata
