Importance of phloem
Witryna7 paź 2024 · Phloem, a major tissue that transports photo-assimilates and mediates long-distance signaling molecules such as small RNAs, hormones, or proteins from a source to a sink (Chen et al. 2024 ), consists of sieve elements (SEs) and companion cells (CCs). These two cell types together form a functional unit of the phloem. WitrynaThe phloem carries food downward from the leaves to the roots. Xylem cells constitute the major part of a mature woody stem or root. They are stacked end to end in the …

Witrynaphloem: [noun] a complex tissue in the vascular system of higher plants that consists mainly of sieve tubes and elongated parenchyma cells usually with fibers and that … WitrynaThe 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.
WitrynaLarge early phloem sieve tubes are involved in conducting, whereas a high share of axial parenchyma in late phloem indicates the importance of the storage function .
