In Your Fridge...

We have seen how different colored plants have different colored pigments.

What fruits or vegetables do you have in your home? Which pigments do you think are in those fruits or vegetables?

Why do you think...?

We can see that for the most part it did not matter what color leaf we used, we still see the four different types of pigments during chromatography.

Hypothesize as to why we see green leaves in the summer, but when the weather gets cooler, the leaves change colors and the other pigments start to show/become dominant.

Isolating Pigments – Results and Discussion

These are the questions posed in class.
First we observed the four different types of chlorophyll pigments present.
Which pigment moved the farthest?
Which pigment moved the slowest?
What is the order of the pigments from slowest to fastest?
