Yes they do. According to my online schooling reading material they do have two halves called valves.
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.
Chrysophyta have silicon cell walls.They are called Diatoms generally.
Diatoms are primarily classified into two main groups: centric diatoms and pennate diatoms. Centric diatoms are radially symmetrical and typically found in aquatic environments, while pennate diatoms are bilaterally symmetrical and often inhabit benthic or sedimentary environments. Both types are characterized by their siliceous cell walls, known as frustules, which contribute to their ecological role in aquatic ecosystems.

The cell wall of a diatom is rich in silicon. It is composed of two overlapping halves, like a petri dish, made of silica that give diatoms their unique intricate patterns and shapes.

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 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 are single-celled organisms with rigid silica cell walls that come in a wide variety of shapes and sizes. They are aquatic microorganisms that play a significant role in marine and freshwater ecosystems. Diatoms are known for their intricate and beautiful glass-like cell walls.

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.

Movement --- Diatoms are able to move by secreting chemicals out of small holes in their cell walls and gliding on the slime:)

Diatoms are eukaryotic, they are a major class of algae and the most common type of phytoplankton. They are unicellular yet exist in colonies in the shape of ribbons.
