Independent variable - Value does not depend on another factor Dependent variable - Value depends on another factor Controlled variable - Kept the same throughout the experiment What are the two key tissues that allow plants to transport water or organic nutrients, respectively, over long distances? - Xylem - water and minerals from roots to shoots Phloem - transports sugars from photosynthesis to where they are needed In the root, plants need to take up more CO2 or O2? - More O2 Is the need for CO2 and O2 in leaves the same when compared to roots? - The difference is because of what the plant needs at that certain spot. The CO2 is needed for photosynthesis to make sugar for the plant Why do you think there is/is not a difference in gas exchange when you compare roots with leaves? - If you look at the apoplast and the symplast, which of the following statements are true? - In the apoplastic route water and solute move along the continuum of cell walls and extracellular spaces If you add sugar to water does the water potential increase or decrease? - Decrease How is osmosis defined? - Diffusion of free water
