Chlorophyll and osmosis, Biology

Assignment Help:
Hello,

I did a experiment: I used 5 salt solutions (0 g/L; 5 g/L; 10 g/L; 15 g/L; 20 g/L), and in each one I cooked beans (25 g) for 5 minutes. At the end, I measured the absorption of light of the water (in which the beans were cooked) with a spectometer. The absorption of green light was increasingly lower(so in the 0 g/L solution there was an absorption of 0,04, and in the 20 g/L there was a 0,01 absorption).

This resulted in my conclusion: the higher the salt solution, the higer the leaching of chlorophyll out of the beans into the water.

BUT my problem is: why? because chlorophyll is too big to pass through the cell walls, and in the higher salt solutions there is plasmolyse, zo the cells don''t burst (as I originally thought).

Thank you for your help!
