Cells in a Cactus Flower

Uninterrupted photographing of amoebas can get boring.
I made lots of pictures of them this morning.
When I went upstairs for a break, I found a beautiful red cactus flower
that had fallen from a plant on the dining room windowsill.
The light for the photography was tricky,
but the variety of cell structures made an interesting exploration.
