Cactus Cells

My sample wasn't well microtomed--it's likely several cell layers too thick. It's still quite beautiful. It looks like the cells contain tiny oceans.

and under higher power I could see the organelles within the cells moving back and forth.

I can understand
how the sea was in it
although it clearly
did something to the ocean
before grabbing it, bloating
in its bag. What does it
hold the ocean in? How do its
tiny belly bubbles shine?
