WebAt the source, glucose is produced by photosynthesis and converted to sucrose (sugar), after which it is transported to the various parts of the plant depending on their requirements for glucose. Active transport is then used to transport the sucrose into the sieve tube cells. Phloem hypertonic conditions are created as a result of this treatment. WebBIOL220 Transport: Phloem.
