General anatomic features of vascular plants

Roots are the primary nutrient pathways

  Lateral roots and cortex act as an absorption zone

  Minerals & water diffuse easily and saturate the apoplast

  The endodermis forms an impermeable zone for solutes

  Diffusion into symplast is regulated by carrier proteins in the plasmalemma

General anatomic features of vascular plants  

  Nutrients & water are transported via vascular bundles

  Nutrients and minerals are stored in the leafs or generative Organs

  Interception of resuspended Ions &

à Stomata

Shoots are the transport pathways
