What cell organelle can be seen changing position in the moving cytoplasm of elodea?

Once the cytoplasm of the amoeba is moving, all the cells in the said cytoplasm will move as well. Consequently all the cell organelles can be seen changing positions. The cytoplasm’s ability to move is dependent on the entire composition of cell organelles that make up the said cytoplasm.

Ithink that its like 15 mph.
