Are diatoms in the plant kingdom?
Diatoms are plant-like protists. They are encased in a symmetrical silica-based structure. Together with various forms of seaweed, they comprise the vary diverse plant-like protists….Classification of Plant-like Protists.

What kingdom are diatoms and dinoflagellates found in?
Molecular phylogeny (gene sequencing) and other characters show they belong to four kingdoms: Kingdom Plantae (e.g. chlorophytes and rhodophytes – green and red algae), the Kingdom Chromista (e.g. phaeophytes – brown algae – dinoflagellates, and diatoms), the Kingdom Protista (e.g. Euglenophytes), and the Kingdom …
What order do diatoms belong to?
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.
Are diatoms microscopic?
Nearly all diatoms are microscopic – cells range in size from 2 µm to 500 µm (= 0.5 mm).
Where are diatoms found?
Diatoms are photosynthesising algae, they have a siliceous skeleton (frustule) and are found in almost every aquatic environment including fresh and marine waters, soils, in fact almost anywhere moist.
Do diatoms belong to dinoflagellates?
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.
What is a diatoms habitat?
Diatoms are found in all freshwater habitats, including standing and flowing waters, and planktonic and benthic habitats, and they can often dominate the microscopic flora.
Are diatoms Chemoautotrophs?
While almost all phytoplankton species are obligate photoautotrophs, both photoautotrophs and chemoautotrophs are included in the phytoplankton. In terms of numbers, the most important groups of phytoplankton include the diatoms, cyanobacteria, and dinoflagellates, although many other groups of algae are represented.
What Kingdom are Penicillium in?
Penicillium, genus of blue or green mold fungi (kingdom Fungi) that exists as asexual forms (anamorphs, or deuteromycetes). Those species for which the sexual phase is known are placed in the Eurotiales.
What Kingdom does diatom belong to?
diatom (dī´ətŏm´, –tōm´), unicellular organism of the kingdom Protista, characterized by a silica shell of often intricate and beautiful sculpturing. Most diatoms exist singly, although some join to form colonies.
Where are diatoms mostly found?
Diatoms are unicellular algae which form distinct and beautiful cell walls from silica. They are widely distributed throughout the upper layers of the oceans of the world, and can also be found in fresh water or moist environments, such as the undersides of plants.
What is the structure of diatoms?
Diatoms have a unique structure in that they have a porous silica cell wall that is split into two halves called frustules. A large upper frustule sits on top of and encloses a smaller lower frustule. The two distinct shapes of a diatom split the Bacillariophyta into two separate classes: the pinnate and centric diatoms.
