WebPhloem - Key takeaways. The main function of phloem is to transport assimilates to sinks via translocation. Phloem contains four specialised cell types: sieve tube elements, companion cells, phloem fibres and parenchyma cells. Sieve tubes and companion cells work closely together. Sieve tubes conduct food matter in the plant. WebFeb 26, 2014 · Here we show that plant xylem from the sapwood of coniferous trees – a readily available, inexpensive, biodegradable, and disposable material – can remove bacteria from water by simple pressure-driven filtration. Approximately 3 cm 3 of sapwood can filter water at the rate of several liters per day, sufficient to meet the clean drinking ...
