Biol 186 UVIC Midterm 1 Rossi's Questions With Solutions How does the ascent of water in a plant take place? Diffusion - short distances Root Pressure - Pushed upward from roots Capillary Action - Cohesion and Adhesion fight gravity Suction Pump - Pulled from roots by leaves. What does ψ (psi) represent? Water Potential - Predicts which direction water will flow. Water moves from higher ψ to lower ψ. Water potential is given as the equation: ψ = ψp + ψs What is ψp, and what does...
