WebbPhloem mostly contains sugar molecules dissolved in water forming a very thick sugary sap, which is food for them. And if you're wondering what these things are over here at the sides, that is some leftover cytoplasm. The cells don't lose all of their cytoplasm. And similarly, this is the cell walls. WebbINTRODUCTION Phloem is a vascular tissue of vital importance to plants since it carries all the photosynthates produced by the leaves and sig- nalling molecules, such as mRNAs, to all plant parts.
