Question

Diffusion and Osmosis Plasmolysis - Elodea leaf in 10% saline 0 minute 2 minutes 5 minutes Figure 5. Elodea cells, before and after treatment with 10% sodium chloride (400x magnification). Question 8. Which green organelle is shown at arrow 1 in the upper left-hand diagram (0 minute), capable of consuming both water and carbon dioxide during photosynthesis? Question 9. What part of the Elodea cell, shown at arrow 3 in the lower diagram, is decreasing in size rather than increasing in size (getting smaller from the 2 minutes to the 5 minutes diagram), due to osmotic pressure changes?
