Water and Ion Transport in Plants: A Comprehensive Overview, Slides of Biology

Gujarat Ayurved UniversityBiology

An in-depth exploration of water and ion transport processes in plants. Topics covered include water potential, mineral uptake, ion transport into xylem, water transport into xylem, endodermis and pericycle, transpiration-cohesion-tension mechanism, and stomata. The document also introduces the pressure flow model for phloem sap movement.

Transport in Plants

Water Transport

• Ψ = ΨS + ΨP

  • solute pressure
    • result of concentration of solute in a solution
  • pressure potential
    • hydrostatic pressure

Mineral Uptake

  • requires facilitated diffusion or active transport proteins
  • proton pump

Ion Transport into Xylem

  • transported into the cortex
  • may move with water or via diffusion

Endodermis and Pericycle

  • endodermis is a selective barrier
    • Casparian strips
  • pericycle
    • transfer cells

Transpiration-cohesion-tension

Mechanism

  • transpiration
  • tension
  • cohesion

Pressure Flow Model

  • explains movement of phloem sap
  • source vs. sink

Pressure Flow Model

    1. high solute concentration at source
    1. increase in hydrostatic pressure
    1. sugars in sink draw water out of phloem
