Key Topics Covered

Water potential and osmosis

Root absorption mechanisms

Xylem transport - transpiration pull

Phloem transport - pressure flow

Stomatal regulation

Calculate and apply water potential

Explain transpiration-cohesion-tension mechanism

Describe pressure-flow in phloem

Understand stomatal opening control

Very important! Transport in Plants chapter tests water potential, transpiration, and translocation mechanisms.

Olympiads require water potential calculations, understanding of solute and pressure potentials, and experimental interpretation.
