To whom it may concern,
I am doing a science fair progect and my research question is: "are
hibernating trees alive" and I am using the four criteria for life to
help me. I took a Red Oak limb and put a drop of sap onto a slide and
looked through a microscope. It is hard to describe what I saw but it
looked like a substance made of fibers with a black dot in the center. I

a central vacuole.
Could you help me?
