Water Potential
In this lesson you will master how water moves through cells by understanding the concept of water potential and why it is essential for life.
Define water potential and explain its components (solute potential and pressure potential).
Predict the direction of water movement using water potential values.
Understand the role of water potential in osmosis, plant water transport, and cell turgor.
Calculate water potential in various scenarios.
Understand osmosis, diffusion, and concentration gradients.
Know how to identify hypotonic, hypertonic, and isotonic solutions.
Use algebra and unit conversion (e.g., pressure in bars or megapascals).
Be familiar with plant cell structure, particularly the cell wall and vacuole.
Conceptual Explanation of Water Potential:
How does water move from the roots of a tree to the leaves at its tallest branches? Why is it dangerous to drink salt water? Learn how water potential, solute potential and pressure potential influence water movement in animal cells and plants by building on key concepts like tonicity and osmosis.
