What are Diatoms?

What are diatoms?
Diatoms are a major group of algae and are among the most common types of phytoplankton.
Diatoms are unicellular organism, although they can form colonies
They have cell walls made of glass
Diatoms belong to kingdom Protista
There are at least 100,000 species of diatoms have been discovered,
Diatoms exist in large numbers in most bodies of water throughout the world. In fact, just one quart of seawater can contain millions of diatoms
They are primary producers and create and are a very large food source in the ocean
Diatoms are autotrophs and produce energy by photosynthesis.As a result,, diatoms need sunlight, carbon dioxide, and water. They are found in the ocean, fresh water, and even moist topsoil
Many Diatoms are microscopic, but some measure a millimeter across.
Diatoms contribute enormous amounts of oxygen to our atmosphere.
Two basic forms of these organisms exist. They are known as Centrales Centrales have radial symmetry and are most often found in oceans and are wheel-shaped. They can be found drifting near the surface, sunlight and absorbing nutrients.Pennales tend to be elongated
Many Pennales live in fresh water streams, swamps, ditches, or on the bottoms of shallow regions of oceans and estuaries.

"..cell walls of glass"?!? Silicon, perhaps, but glass? ..psss-sshaw. Misinformation, no?

[@MooMooMath]

Thanks for the feedback. You are correct, I should have said walls of silica that looks like glass. Sorry for any confusion.

[@chycarlisle3483]

It's actually Opal, which is a form of quartz. Quartz is Glass. So yes they are made of glass.

[@Makethemhearragtime]

Forensics call it glass legally.

Yes indeed the they are glass made of opaline silica which is an amorphous solid just like glass. Unlike another commenter says their cell wall is not made of quartz and quartz is not an amorphous solid its a crystalline solid.

I hope you enjoy this video on diatoms. As pointed out by Theo A Artz the walls are not made of glass like a bottle of soda. I should have said the walls are made of silica and look like glass.

Good and interesting vedio fulltoss

Kingdom Protista no longer exists. It was used as grab-bag term for several unrelated unicellular organisms (to include diatoms) which have since been sorted into different new taxa.

[@MooMooMath]

Thanks for the feedback. According to UC Berkley " the word "protist" is a convenient term to mean "eukaryote that isn't a plant, animal, or fungus."

Interesting info. Thanks.

[@TKO67]

so many uses for the dust. especially the food grade

[@TALESSIDE]

Silicon is like glass but not exactly glass

[@cedricproper5256]

Not bad. Not bad at all.

[@spiritualscientist9869]

00:20 Did u say "Diatoms have cell membranes made of glass" ????

[@troy.u3297]

silica is glass in non-crystalline form

[@questionreality6003]

too much CO2 bathing the sea surface where they live kills them per carbonic acid thus made?

[@nethventuregaming1474]

Is diatom a species?or a class?

[@Racheal700]

Not really glass..a little misleading..

[@Mmdmade]

Diatoms, one-​celled organisms, take silicon and oxygen from seawater and make glass, with which they construct tiny ‘pillboxes’ to contain their green chlorophyll.

pov ur in class

[@tron-8140]

I dont think we should be getting science education from a kid using a dollarstore webcam as a microphone. He is really good at reading wikipedia though.
