What is the Difference Between Sieve Tubes and Companion Cells

Unlike xylem (which is composed primarily of dead cells), the phloem is composed of still-living cells that transport sap. The sap is a water-based solution, but rich in sugars made by photosynthesis. These sugars are transported to non-photosynthetic parts of the plant, such as the roots, or into storage structures, such as tubers or bulbs. WebbAs a fundamental tissue in the plant body, phloem functions extend from its primary process of transporting sugar to include transporting signalling molecules like mRNAs, …
