What is the function of Pteris vittata?
A Chinese brake fern (Pteris vittata) shows excellent arsenic hyperaccumulation properties in contaminated soil. It concentrates arsenic in aboveground biomass, which is a primary requirement for efficient phyto-remediation.
What is the function of the stele?
The stele functions in the transport of water, nutrients, and photosynthates, while the cortical parenchyma fulfills metabolic functions that are not very well characterized.
