However, some centric diatoms can move and some …
WebThrough the raphe, the living diatom secretes mucilage, with which it may attach to a substrate or move by gliding over the substrate. Within their silica walls, diatoms show a typical level of eukaryote organization. Living diatoms contain several chloroplasts, where photosynthesis takes place.
WebDiatoms divide vegetatively, and, when resources are not limiting, at a fast rate. Diatoms respond to a certain number of environmental and biological variables (light, water temperature, substratum type, water velocity, mineral composition and content, nutrient availability, grazing) by shifting their community composition and growth forms. WebOn the water surface of densely populated cultures occasionally float diatoms, which are in mutual mechanical contact and show a relative movement. Surprisingly, there also is the case that diatoms can move on or near the water surface without having such a contact.
