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 ma...
