One goes up... and one goes down. I was a college freshman in Botany 101 when I first learned about xylem and phloem, the two transport tissues which carry water and nutrients up and down a tree's ...

With our sustained high summer temperatures plants need a continuous source of water. Water moves from the soil into and throughout a plant delivering water and nutrients via a pipe-like vascular ...

We have investigated the consequences of endogenous limitations in oxygen delivery for phloem transport in Ricinus communis. In situ oxygen profiles were measured directly across stems of plants ...

Owing to recent advances, plant vascular developmental can now be described from early specification during embryogenesis up to late differentiation events. Plant vascular tissues display both ...

This is a preview. Log in through your library . Abstract Recent work contradicting both the assumptions of the Cohesion Theory, and the tensions measured in the xylem sap by the pressure-chamber, is ...
