A tale of two plants (videos)

First is a house plant of unkown species. Leaf section. It is a long leafy vine. The last video is an aloe plant. Nikon 100 1.25.

Very interesting. Were you ever able to actually see the stoma close or open, or does that happen over hours?

No Mitch, I didn't see any movement of the stoma/stomata. Just what I suspect are cytoplasmic inclusions moving around. I've uploaded a few more videos. The last is very high magnification, hence the worse quality, which really details what I suspect are the inclusions. Thanks for looking

Very interesting video. The image quality is excellent and some nice detail of stomata structure can be seen.

Thanks Dave

Can anyone confirm what these small moving particles are?

Whatever they are, I have seen and photographed them many times before, in Clostereum and other Desmids.

Yea, I've seen them before also. I'd just like to know what they are exactly.

Taken from Wikipedia:

The inclusions are small particles of insoluble substances suspended in the cytosol. A huge range of inclusions exist in different cell types, and range from crystals of calcium oxalate or silicon dioxide in plants,[4][5] to granules of energy-storage materials such as starch,[6] glycogen,[7] or polyhydroxybutyrate.[8] A particularly widespread example are lipid droplets, which are spherical droplets composed of lipids and proteins that are used in both prokaryotes and eukaryotes as a way of storing lipids such as fatty acids and sterols.[9] Lipid droplets make up much of the volume of adipocytes, which are specialized lipid-storage cells, but they are also found in a range of other cell types.
