Phloem is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to the rest of the plant. This transport process is called translocation. In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Ancient Greek word φλοιός (phloiós), meanin… WitrynaThis tissue is composed of “various specialised cells” like “ phloem fibres, phloem parenchyma cells” called sieve elements. Conclusion The importance of the “transport system in plants” cannot be defined in one word because this is the process by which plants get their required nutrition and growth by which they can survive in nature.
