strucutre, support, &nbsp;transport &nbsp;mvmt</p>

<p>

MT = microtubule &nbsp;diam &nbsp;25 nm. &nbsp;involved in mitotic spindle &nbsp;and in cilia, flagella,&nbsp;

and transport.</p>

<p>

intermed fialments: diam &nbsp;10 nm. &nbsp;(struc support... like springs in a mattress)

they resist mechanical stress (like springs) and retain shape.</p>

<p>

microfilaments: &nbsp;diam &nbsp;abt 7 nm... &nbsp;&nbsp;movement of the cell from within...</p>

<p>

eg in mitosis &nbsp;(pinched in the middle) &nbsp;or

ameboid motion... &nbsp;with pseudopods... engulf food.</p>
