What are diatoms ... Diatoms are delicate unicellular organisms that have a yellow-brown chloroplast that enables them to photosynthesize. Their cell walls are made of silica almost ... With these they can move over a surface. In the picture of the cleaned diatom above the raphe can be seen as the thin central horizontal line.

But also desmids, diatoms and bluegreen algae have a mechanism for movement. How diatoms move is not completely understood. Only the pennate ones can. It seems that through the groove running in the length of the cell wall, called the raphe, tiny fibrils protrude that vibrate in one direction.

Some diatoms can move around by squirting stuff out of slits in their cell walls. There are about 10,000 known diatom species. Sorry, I couldn't resist --- I warned you I was an algae nerd :) The most common myth about diatoms is that they are caused by a certain light level (some say low, others high) or just old bulbs.
