Development) The term phloem originates from the Greek word‚ phloios‚ meaning “bark”. (Merriam-Webster) In vascular plants‚ phloem is the living tissue that carries organic nutrients‚ particularly sucrose‚ to all parts of the plant where needed. (Lalonde S‚ 2004) Phloem’s main job is to move sugars from the source tissue (ex. photosynthetic leaf cells) to sink tissues (ex. non-photosynthetic root cells or developing flowers). Molecules like proteins and mRNAs also are transported to parts of the plant by
