Xylem cells transport water from the roots to other parts of the plant. Phloem cells transport sugary water from the leaves to the rest of the plant. Xylem cells run inside stems of plants from ...

In the winter, when deciduous trees have no leaves, the water pressure in the sap becomes positive. A flow occurs where water moves up in the xylem and cycles down in the phloem (food conducting cells ...

A combination of lineage tracing and single-cell RNA sequencing reveals how xylem and phloem parenchyma cells in the secondary tissue of Arabidopsis root mature gradually. Upon root barrier injury ...
