Diatoms
diatoms
Mainly Diatoms
Protists are made up of very large, diverse group of organisms, including the plant-like protists (algae), fungi-like protists, and the animal-like protists (protozoans). They are all eukaryotic, and most are unicellular.
I believe you a thinking about Diatoms. They have a shell, not a cell wall, made of silica, the same material glass is made of. They are a spectacular sight under a microscope. Because of their Strong rigid shell and reflective properties they are used in many commercial products like reflective paints, abrasives, and formerly cosmetics.
Diatoms are microscopic plants (phytoplankton) found in oceans and lakes. Their cell wall is made of Silica which remain after the diatom dies. Diatoms are single celled, photosynthetic algae this means that they are producers!!

Diatom cell walls are composed of silicon dioxide.
what are protists made of
its different because walls and plants are made from different stuff
A cell wall made of cellulose, hemicellulose and pectin is one of the unique features of plant cells. They also contain chloroplasts, which are photosynthetic organelles (that are not found in animal cells).
Animals and most protists don't have a cell wall .All plants , fungi and Bacteria have cell wall .Cell wall of plants id made up of cellulose . In bacteria it is made up of peptidoglycan while in fungi it is made up of chitin .
