Flagella
It is a main duty that the flagella produces the driving force that is necessary for swimming with a hair-shaped organelle.
I am separated structurally by organism with a nucleus flagella and eubacterium flagella, old bacteria flagella.
From the sperm of the animals and plants, I am seen in and an alga such as the euglena and a protist widely.
As for the length, severalμm - dozens ofμm, a diameter of the cross section are approximately 200-300nm.
Even a normal light field model optical microscope can confirm, but can observe it more clearly if it is a phase contrast microscope and dark-field microscope, a differential interference microscope.
Flagella it in itself does flexure actively, and the flagella of the organism with a nucleus has ability to exercise.
Microtubule placement to be called 9+2 structure is observed when I observe a section of the flagella in an electron microscope.
I call this part making the core of the flagella axoneme (axoneme).
There is a protein molecule motor called the dynein between this microtubule.
Dynein does hydrolysis of ATP and takes out energy, and it is thought that flexure of the flagella is caused because this is converted into sliding movement between the microtubule (A Kosuge and B Kosuge).
The surface of the flagella is a cell membrane.
Furthermore, the outside needs the uncooked food with various kinds of ornamentation structure, too
