Cysts are ovoid, 8-14?m long by 7-10?m wide, with two or four nuclei and remnants of organelles visible. |
|
In eukaryotes, the movement of bivalent molecules along cytoskeletal filaments enables organelles and vesicles to be transported from one location in the cell to another. |
|
You should learn that the cytoskeleton is both a muscle and a skeleton, and is responsible for cell movement, cytokinesis, and the organization of the organelles. |
|
Unlike eukaryotic cells, prokaryote cells lack membrane-bound organelles. |

Although the many organelles within the cell are enclosed by membranes, they are highly dynamic, and many are in constant communication with each other. |
|
It involves a reorganization of the cell cytoskeleton and intracellular organelles and eventually results in a specific cell response: directional migration or growth, oriented division, oriented secretion, etc? |
