I don't have the material now, but I once caught two aspects of 'movement'
in a series of stills.  I'd germinated Pinus aristata seeds on agar in
plastic Petri's.  I then inverted the dishes on a light scope and was able
to bring them into focus (through the thickish plastic) at 100 and 400x as
I recall. The root tips seemed be shedding living cells as they grew.  I
watched and photographed the growth (or at least translation across the
field), the slow shedding of cells, and the cytoplasmic circulation within
the cells.  This was on Askell Love's Zeiss Ultraphot in Boulder around
1970.  It was distinct enough that once could now video it, especially
with a time lapse.
