Is Bacillariophyta a diatom?
Bacillariophyta A phylum of algae comprising the diatoms. These marine or freshwater unicellular organisms have cell walls (frustules) composed of pectin impregnated with silica and consisting of two halves, one overlapping the other.
What are members of phylum Bacillariophyta?
Bacillariophyta is a phylum of the kingdom Protista, consisting of mostly unicellular aquatic algae commonly referred to as Diatoms. Xanthophytes are the yellow-green algae whereas Chrysophytes are the golden-brown algae.
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.
What is the common name for Bacillariophyta?
diatoms

Why Bacillariophyta are called diatoms?
Indeed, the common name, diatom, is derived from two Greek roots that mean cut in two as a reference to the structure of the frustule. The valves are usually highly ornamented with punctae, striae, costae, and other variations in the wall (Figure 1).
What is an example of a diatom?
Pinnularia is an elongated, elliptical diatom covered in a mucilaginous layer. The genus belongs to the family Pinnulariaceae, order Naviculales, class Bacillariophyceae. Navicula is a genus that belongs to the family Naviculaceae, order Naviculales, 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 classification is Bacillariophyta?
BacillariophyceaeDiatom / Scientific name
Are diatoms phytoplankton or zooplankton?
Diatoms are a type of plankton called phytoplankton, the most common of the plankton types. Diatoms also grow attached to benthic substrates, floating debris, and on macrophytes. They comprise an integral component of the periphyton community.
Is diatom a seaweed?
As nouns the difference between seaweed and diatom is that seaweed is any of numerous marine plants and algae, such as a kelp while diatom is a group of minute unicellular algae having a siliceous covering of great delicacy, now categorized as class , now obsolete.
How do Bacillariophyta move?
Some pennate diatoms are capable of a type of locomotion called “gliding”, which allows them to move across surfaces via adhesive mucilage secreted through the raphe (an elongated slit in the valve face).
How do Bacillariophyta reproduce?
Diatoms primarily reproduce asexually by binary fission, similar to prokaryotes. During binary fission, the two valves of the frustule are separated and each new cell forms a new valve inside the old one.
