Plant Water Relation
Description: Diffusion: Spontaneous movement of particles, Osmosis: Movement of water across membranes, Osmotic Pressure: Pressure from osmosis, Facilitated Diffusion: Assisted membrane transport.
Description: Factors affecting water absorption in plants include root surface area, water potential gradient, and active transport mechanisms in roots.

Description: Root Pressure Theory posits upward water movement due to root osmotic pressure. Capillarity Theory explains water rise in tubes. Cohesion-Tension Theory involves transpiration pull in xylem.
Description: Mechanism of sugar transport through phloem involves pressure flow mechanism and active transport. Cuticular transpiration occurs through the plant's waxy cuticle layer.
Description: Lenticular transpiration happens through lenticels on stems. Stomatal transpiration occurs through stomata on leaves. Stomata open for gas exchange and close to reduce water loss. Transpiration regulates plant temperature and facilitates nutrient uptake.
Description: Plant water relations involve root absorption, root hair adaptation, and imbibition, crucial for water uptake and plant hydration.
