- n. (botany) tissue that conducts synthesized food substances (e.g., from leaves) to parts where needed; consists primarily of sieve tubes
After a female borer lays its eggs on an ash tree, the larvae burrow through the bark and feed on vascular tissue called the phloem, cutting off the tree's supply of nutrients and starving it to death.
In dicots the phloem is a distinct layer separated from the xylem by a thin layer of cambial tissue
There is a ring of small cambium cells around this merging into the phloem, which is composed of irregular cells, with pretty thick, but soft walls.
In the end, she would help him form cambia on the outside of his phloem.
The parasitic plants germinate on white fir branches and force their roots into the phloem of the host branch.
The leafhopper acquires the phytoplasma while feeding by inserting its stylet a long, slender hollow feeding structure into the phloem of infected plants and withdrawing the phytoplasma with the plant sap.
Phytoplasmas live in the phloem food conducting tissues of their host plant.
The disease is spread from plant to plant primarily by phloem feeding leafhoppers.
—In autumn, with a great creaking and a snapping of twigs, they break away from trunks grown thick with bark and phloem, which become husks with jagged tips, or later often topple from sheer grief.
