Periderm

The outer protective layer in the stems and roots of woody plants.

Transpiration

The process by which water is absorbed by plant roots, moves through plants, and evaporates primarily from leaves, playing a key role in plant water regulation and nutrient uptake.

Cotransport

A membrane transport mechanism that simultaneously moves two substances across a cell membrane in the same direction, one typically driving the movement of the other.

Transpiration

The process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released into the atmosphere.
