They should, unless they're dead.
pennate diatoms
as diatoms move through water they filter particles through their two silica shells
diatoms
Movement --- Diatoms are able to move by secreting chemicals out of small holes in their cell walls and gliding on the slime:)
Most diatoms are non-motile, simply being carried by currents and turbulence - however, some types move via flagellation (the swimming motion of small hair-like features called 'flagella'). Flagella are projections from the cell body which are moved back and forth (flagellated) to provide motion. Identical in structure to flagella (but somewhat shorter in length), cilia are present in mammals primarily to facilitate the movement of fluids and mucus across tissues/membranes.
Yes, diatoms are classified within the division Chrysophyta, which includes golden-brown algae like diatoms.
Diatoms are algae, diatoms are protists. Diatoms are placed in the division Bacilliariophyta, which is distinguished by the presence of an inorganic cell wall composed of hydrated silica.
Diatoms account for 23% of the primary productivity of the world, that's what they do!
diatoms are producers, not decomposers. they are photosynthetic organisms
The phylum for diatoms is Bacillariophyta. Diatoms are a type of algae that belong to this phylum and are characterized by their unique silica cell walls.
Most Diatoms are Photosynthetic but some have evolved to be heterotrophic
Diatoms are microscopic. Diatoms range in size from about 2 microns to about 500 microns or equal to the width of a human hair.
