Types of Single-Celled Algae with Silica Shells

Diatoms are single-celled algae that have silica shells, also known as frustules. These microscopic algae are a type of phytoplankton and are found in various aquatic environments, including oceans, lakes, rivers, and even damp soil. Diatoms play a crucial role in the global carbon cycle and are known for their intricate and beautiful glass-like shells.

Diatoms are a diverse group, with an estimated 100,000 species, and they are considered one of the most ecologically significant groups of organisms on Earth. Their silica shells are a distinctive feature that sets them apart from other types of single-celled algae.

Citation: - "Diatoms are a major group of algae, and are among the most common types of phytoplankton. Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons (e.g. Fragilaria), fans (e.g. Meridion), zigzags (e.g. Tabellaria), or stellate colonies (e.g. Asterionella). Diatoms are producers within the food chain. A unique feature of diatom cells is that they are enclosed within a cell wall made of silica (hydrated silicon dioxide) called a frustule." - Wikipedia

Radiolarians are another type of single-celled algae that possess silica shells. These marine planktonic organisms are known for their intricate and delicate mineral skeletons, which are composed of opaline silica. Radiolarians are an important component of marine ecosystems and are particularly abundant in the upper layers of the ocean.

Citation: - "Radiolarians are amoeboid protozoa that produce intricate mineral skeletons, typically with a central capsule dividing the cell into the inner and outer portions of endoplasm and ectoplasm. They are found as zooplankton throughout the ocean, and their skeletal remains make up a large part of the cover of the ocean floor as siliceous ooze." - Wikipedia

These two types of single-celled algae, diatoms, and radiolarians, are notable for their silica shells and play significant roles in aquatic ecosystems.
