Luckily a few weeks ago, she asked me a question when my brain was fully functional. What luck!
Charlotte bit into a piece of celery and one of the strings remained dangling from the stalk. She asked me what it was. I told her it was the xylem, the transport tube that brings water to top of the plant. I love when I remember things from high school biology. I also remembered the experiment we did in high school to demonstrate the xylem.


Now Charlotte knows what the strings in celery are used for. I guess some of that seemingly useless information I learned in high school came in handy after all. Little did I know then that I would have a precocious five year old one day and that information would be really handy.
See kids, stay in school... you might need a random fact from biology one day.
