The presence of membrane bound organelles in eukaryotic cells allows them to overcome this limitation, which exists in prokaryotic cells. (1) prokaryotic cells lack a cytoskeleton, whereas eukaryotic cells may include microfilaments, microtubules and intermediate filaments. (1) the presence of microtubules and microfilaments in eukaryotic cells, together with the existence of motor proteins, allows molecules, vesicles and organelles to be moved around the cell rather than relying on diffusion. (1) diffusion over long distances may not be sufficiently rapid to keep up with the requirements of the cell. 8 person is successful, identify the fish species of the roadside attractions of the following locations (all of which have been featured on the announcements slides! a. gananoque, ontario 1. b. selkirk, manitoba 2. c. sault ste marie, ontario 3. d. campbellton, new brunswick 4. e. dominion city, manitoba 5. f. upsala, ontario 6. g. westport, ontario 7. h. kenora, ontario 8.
