PL1) Describe the difference between diffusion, osmosis, and active transport of molecules across a cell membrane.
PL2) What are osmotic potential, pressure potential, turgor pressure, and water potential? Why are these concepts
important to plant cells?
PL3) Explain the cohesion-tension theory. Contrast this with the pressure flow hypothesis. Why are these concepts
important to a plant?
PL4) Observe the diagram below, and give the number that corresponds with each term listed: cellular respiration,
photosynthesis, sugar, water, oxygen, carbon dioxide, sunlight, mitochondrion, chloroplast, ATP
