Why are Bacillariophyta called diatoms?
Bacillariophyta A division of microscopic algae (known as diatoms) which are mostly unicellular, but which may be colonial or filamentous. The cell wall (frustule) is composed of silica and consists of two halves, one of which overlaps the other like the lid on a box.
What are features of Bacillariophyta?
General Characteristics. The Bacillariophyta, commonly known as diatoms, are a group of unicellular (though sometimes colonial), diploid, golden or brown-pigmented algae, most of which occur in freshwater and marine habitats; just a few live on land. The aquatic species can be planktonic or benthic.

Which of the following is not diatom?
Nostoc is classified as blue – green algae, and also as a cyanobacterium. It is photosynthetic, and one of the oldest living organisms on this planet. Despite these features, Nostoc’s cell wall is made of peptidoglycans and an outer lipid and protein membrane. It is therefore not a diatom.
What are diatoms classified?
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.
What is the Colour of Bacillariophyta?
General Characteristics. The Bacillariophyta, commonly known as diatoms, are a group of unicellular (though sometimes colonial), diploid, golden or brown-pigmented algae, most of which occur in freshwater and marine habitats; just a few live on land.
Where are Bacillariophyta found?
The diatoms (Bacillariophyta) are the most species-rich group of autotrophic algae, found in fresh, brackish, and marine waters worldwide, and also in damp terrestrial habitats. They are well represented in marine phytoplankton and may account for 20% of global photosynthetic carbon fixation.
What is the family of diatoms?
Diatoms are formally classified as belonging to the Division Chrysophyta, Class Bacillariophyceae.
How many species of Bacillariophyta are there?
Bacillariophyta made up 235 species, Chlorococcales 131 species, Cyanophyta 65 species, Chrysophyta 9, Dinophyta 9, Euglenophyta 8, and Volvocales 5 species. Rhodophyta consisted of a single species, Chantransia chalybea Fries. Melosira varians, Aulacoseira granulata, A. italica (Ehr.)
What is meant by chlorophyceae?
Definition of Chlorophyceae : a class of algae (division Chlorophyta) distinguished chiefly by having a clear green color, their chlorophyll being masked or altered little or not at all by other pigments.
What is the meaning of Chrysophyta?
Definition of Chrysophyta : a division or other category of algaewith pigments localized in yellowish green to golden brown chromatophores and usually with a cell wall made up of overlapping halves and that includes the classes Xanthophyceae, Chrysophyceae, and Bacillariophyceae.
