MadSci Network: General Biology |
To start with, you seem to have a major misconception. Even the smallest mite is much, much larger than a typical human body cell. Here is a link that will help: http://www.cellsalive.com/howbig.htm As to how many cells make up the smallest mite, I'm not at all sure nor am I able, in the short run, to find out what the smallest mite is. I'm not sure even a mite expert would know. Mites of a given kind do vary in size, I have found. What you may be thinking about is rotifers, whose bodies, I was taught many years ago, consist of a fixed number of cells that was in the 20 to 30 range. My research on your questions has cured me of that myth. I discovered that rotifers are thought to have a fix number of body cells but that it is on the order of 1000. Here is a reliable link: http://en.wikipedia.org/wiki/Rotifer This fact is more amazing given that most rotifers are not much, if at all, larger than some large, unicellular organisms like amoebas and ciliates like Paramecium. I found one rotifer source that went as far as to itemize the cell number of rotifer organs. http://www.micrograp hia.com/specbiol/rotife/homebdel/bdel0100.htm Given that such a tiny animal as a rotifer has 1000 cells, I'd expect the smallest mite to have many more. Sorry I was not able to give you a definite answer. I hope that you have learned some things and that this has helped.
