4 cards from this section. Quick, good the night before a test.
What force primarily drives the ascent of sap in plants?
Think about what happens when water evaporates from leaves.
Which force allows water molecules to stick to the xylem walls?
Consider how water interacts with surfaces.
What is the main force behind the ascent of sap in plants?
Think of how water exits through the leaves and creates pressure.
True or False: Cohesion helps keep the water column intact during ascent.
Consider how water molecules interact in a chain.
Given a plant species with a high rate of transpiration, predict its water uptake mechanisms and the role of each force discussed.
Consider the interrelations of the forces and how they enhance each other's effects.
Design an experiment to demonstrate the effects of different environmental factors on transpiration rates. Outline your hypothesis and expected outcomes.
Focus on how environmental changes impact the driving force of transpiration.
