Diatoms
Diatoms are photosynthetic organisms with a glassy two-part cell wall made of silica. These cell walls, called frustules, have intricate patterns and are responsible for the diverse shapes and sizes of diatoms.
No, not all protists have cell walls. Some protists have cell walls made of various materials like cellulose or silica, while others do not have cell walls at all. The presence or absence of a cell wall depends on the specific type of protist.
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!!
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.

Some protists have a cell wall made of various materials, such as cellulose, silica, or calcium carbonate. However, not all protists have a cell wall; some have cell membranes instead.
No, not all protists have cell walls. Some protists have cell walls made of various materials like cellulose or silica, while others do not have cell walls at all. The presence or absence of a cell wall depends on the specific type of protist.
Diatoms are photosynthetic protists with boxlike double shells known as frustules. These frustules are made of silica and provide diatoms with protection and structural support. Diatoms are an important component of aquatic ecosystems and play a significant role in the global carbon cycle.
Protists can have either a cell wall, a cell membrane, or both. The presence of a cell wall in protists varies among different species and can be made of various materials such as cellulose, silica, or chitin. The cell membrane is common to all protists as it is essential for controlling the movement of molecules in and out of the cell.

Plant cell walls are composed of cellulose, while fungal cells walls are composed of chitin. Both are long-chain starches comprised of many glucose subunits.
