Unit I: 
Plant-Water relations

Soil water, diffusion and osmosis (DPD, OP, TP, water Potential), imbibition, Plasmolysis, ascent of sap, transpiration: stomatal structure, mechanism and significance of transpiration.

Mineral nutrition: Role of micro and macro elements, ion uptake: chelating reagents and siderophores, deficiency and toxicity symptoms, hydroponics.

Unit II:
