Marine algae can be divided into six groups: green, red and brown algae, euglenophytes, dinoflagellates and diatoms. Dinoflagellates and diatoms are important components of marine algae and have their own sections below. Euglenophytes are a phylum of unicellular flagellates with only a few marine members. Not all algae are microscopic.
Protozoology: the study of protozoa; Phycology/algology: the study of algae; Parasitology: the study of parasites; Immunology: the study of the immune system; Virology: the study of viruses; Nematology: the study of nematodes; Microbial cytology: the study of microscopic and submicroscopic details of microorganisms
By 1954, Protozoa were classified as "unicellular animals", as distinct from the "Protophyta", single-celled photosynthetic algae, which were considered primitive plants. [25] In the system of classification published in 1964 by B.M. Honigsberg and colleagues, the phylum Protozoa was divided according to the means of locomotion, such as by ...
Its field of study therefore overlaps with the more traditional disciplines of phycology, mycology, and protozoology, just as protists embrace mostly unicellular organisms described as algae, some organisms regarded previously as primitive fungi, and protozoa ("animal" motile protists lacking chloroplasts).
The green algae are subdivided into the chlorophytes and charophytes. It is very rare for green algae to become parasitic. [citation needed] Prototheca moriformis belongs to the subdivision Chloroplastida. P. moriformis is a green algae that lacks chlorophyll and has turned to parasitism. It is found in sewage and the soil.
Microorganisms make up about 70% of the marine biomass. [4] A microorganism, or microbe, is a microscopic organism too small to be recognised adequately with the naked eye. In practice, that includes organisms smaller than about 0.1 mm. [12]: 13
A protist (/ ˈ p r oʊ t ɪ s t /) is any eukaryotic organism (one with cells containing a nucleus) that is not an animal, plant, or fungus.The protists do not form a natural group, or clade, since they exclude certain eukaryotes with whom they share a common ancestor; [a] but, like algae or invertebrates, the grouping is used for convenience.
Research on loricae has provided insights into the evolutionary adaptations and ecological strategies of microorganisms. Studies have focused on the structural diversity, material composition, and the genetic mechanisms underlying lorica formation.
