... enzymes to eat thru the outer slimy layer that surrounds the egg cell. It has concentrated all of its mitocondria to the end where there is the flagella for motility. The egg cell is full of maternal mRNA that are silenced till fertilization. It also has vesicles just under the plasma membrane ...

... ultimately signals which way the flagellum should turn, resulting in either forward movement or change in direction. Theoretically, because the flagella at both ends are on the same bacteria and therefore in approximately the same region of whatever solution the bacterium is in, should they ...

... parallel and interconnected actin bundles(because that falls under microvillus). A microbiology professor of mine suggested we called EK cilia and flagella "Undulipods" and use cilium for all the other uses of the word. However, though probably correct, such a distinction would be impossible ...
