Algae in the Cupboard

I ransacked the house.

I think I disturbed my poor mother who had, with my help, just organized the pantry.

I was determined not to appear as though I hadn't tried.  I took pictures of everything I could find in which algae derivatives are commonly used, and all of if was void of the magical ingredients: carrageenan, alginates, and beta carotene.

I searched the refrigerator: nothing.

This couldn't be.  My classmates had completed the assignment with ease -- what was wrong with my cupboards?

I came to school, guilty and empty handed, to ask Mrs. Richardson what I could do.

Sadly, I couldn't get to the store to take pictures of their algae, so I took another good piece of advice and, this next night, filtered through bathroom supplies.

At long last, I found it! I found carrageenan in my toothpaste!

That's right, my toothpaste contains an algae derivative.

My cell phone camera has quality to poor to see it, but the red circle is around the algae!
