What is the scientific name for diatoms?

Bacillariophyceae
Diatom/Scientific names

Diatom, (class Bacillariophyceae), any member of the algal class Bacillariophyceae (division Chromophyta), with about 16,000 species found in sediments or attached to solid substances in all the waters of Earth.

Why diatoms are called Bacillariophyta?

Individuals usually lack flagella, but they are present in male gametes of the centric diatoms and have the usual heterokont structure, including the hairs (mastigonemes) characteristic in other groups. Diatoms are often referred as “jewels of the sea” or “living opals” due to their optical properties.

How do scientists classify diatoms?

Diatoms are formally classified as belonging to the Division Chrysophyta, Class Bacillariophyceae. The Chrysophyta are algae which form endoplasmic cysts, store oils rather than starch, possess a bipartite cell wall and secrete silica at some stage of their life cycle.

Is dinoflagellate a diatom?

Diatoms and Dinoflagellates. There are many different groups of phytoplankton species found in the world’s oceans, but among the most common are diatoms and dinoflagellates. There are several features of a phytoplankton cell that can identify it as a diatom or dinoflagellate.

How are puncta on intercalary bands irregularly arranged?

Puncta on intercalary bands are irregularly arranged (Cupp 1943). The axis through the centre point of the two valves of a frustule. This axis is perpendicular to the valve face. Features that provide support to other structures in the cell. Other cylindrical diatoms, such as Detonula pumila.

What kind of group do diatoms belong to?

Diatoms belong to a large group called the heterokonts, which include both autotrophs such as golden algae and kelp; and heterotrophs such as water moulds. The classification of heterokonts is still unsettled: they may be designated a division, phylum, kingdom, or something intermediate to those.

How are pads and stalks produced in diatoms?

In diatoms, a structure joining adjacent cells or attaching a solitary cell to a substrate through the secretion of mucilage (can be a mucilage stalk in this case). These pads and stalks are produced by strutted processes (Round 1981). In diatoms, the hard and porous silica cell wall (Horner 2002).

How are the centric and pennate diatoms different?

Diatoms are divided into two groups that are distinguished by the shape of the frustule: the centric diatoms and the pennate diatoms. Pennate diatoms are bilaterally symmetric. Each one of their valves have openings that are slits along the raphes and their shells are typically elongated parallel to these raphes.
