Photosynthesis
They live in the sand sediment and drift along in the upper intertidal zone along the coastline. Diatoms form the "bubbles" that look like golden brown foam at the waters edge.
Most diatoms are photosynthetic (they use sunlight to provide them with energy), though some absorb soluble nutrients from their environment.
Diatoms are single celled algae.
Diatoms are usually microscopic, but they can be 2mm in length. Marine diatoms are a yellowish brown colour.
Photosynthesis
Diatomaceous Earth. It's used as an anti caking agent in food, as and anhelminthic and as an external anti-parasitic.
The cell wall of diatoms are very thick and remain long after the diatoms die. when the cell wall remains of many dead diatoms clump together, they form a crumbly, abrasive substance called diatomaceous earth or diatomite.============================================The rock type called Chalk is also made of diatom skeletons.
Diatoms are a form of algae found almost everywhere. Commonly diatoms refers to the silica exoskeleton left behind when the alga dies. White Cliffs of Dover made from billions of diatom skeletons.
Diatoms are two atoms of the same element bonded together. The only diatoms that form are Br2, I2, N2, Cl2, H2, O2, and F2. You can remember these diatoms using BrINClHOF (brinklehoff) as a mnemonic. Diatoms are drawn with a dash (-) in between the two atoms like so: Br-Br, I-I, N-N, etc.

pennate diatoms
Diatoms are single celled algae.
diatoms are a microalgae group
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.
