How are phloem cells adapted
WebThe cells that make up the phloem are adapted to their function: Sieve tubes - specialised for transport and have no nuclei. Each sieve tube has a perforated end so its … 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…
