They technically are unicellular, because each cell performs the basic functions for life. They might be looked upon as multicellular, because they are always found in visible groups, and they seem to be working together as if they were unified as one organism.
Living beings can be classified into different groups based on their characteristics, such as cellular structure (prokaryotic vs. eukaryotic), mode of nutrition (autotrophs vs. heterotrophs), and number of cells (unicellular vs. multicellular). Additionally, living beings can be classified into domains (Bacteria, Archaea, Eukarya) and kingdoms (e.g., Animalia, Plantae, Fungi) based on evolutionary relationships.
Because each lichen has a symbiotic association of an alga with a fungus, hence it is difficult to classify them. Depending on their gross morpholoy we can classify these as crustose, foliose and fruticose only.
Opinions about how to classify life vary. In one system, the kingdoms are: bacteria, archibacteria, protista, animalia, plantae, fungi. For other classifications, check the Wikipedia article on "kingdom (biology)".
The three main characteristics used to determine kingdoms in taxonomy are cell type (prokaryotic or eukaryotic), cell structure (unicellular or multicellular), and mode of nutrition (autotroph or heterotroph). These characteristics help classify organisms into different kingdoms based on their fundamental biological features.
The five main groups scientists use to classify living organisms are: kingdom, phylum, class, order, and species. Each group represents a different level of classification based on shared characteristics and evolutionary relationships.
The objective of unicellular organisms is to survive and reproduce by carrying out essential functions such as obtaining nutrients, metabolizing, and responding to their environment. For multicellular organisms, the objective is similar, but they achieve it through specialized cells that work together to maintain the overall health and function of the organism.
The flatworm is one portion of the phylum Platyhelminthes. "Platy" meaning flat, and "helminthes" translating to worm. All species belonging to the Platyhelminthes phylum have two cell layers because their bodies consist of an outer skin and also an incomplete gastrovascular system. Therefore, all flatworms are multicellular.
Kingdom Protoctista is difficult to classify because it consists of diverse organisms with unique characteristics that don't fit neatly into other kingdoms. They are grouped based on mostly on their mode of nutrition, locomotion, and reproduction. For example, Protozoa: Unicellular organisms that primarily obtain nutrients through phagocytosis, such as Amoeba. Algae: Photosynthetic protists that can be unicellular or multicellular, like Chlamydomonas. Slime molds: Protists that exhibit characteristics of both fungi and amoebas, such as Physarum polycephalum.
Living things are divided into kingdoms based on several key properties, including cell type (prokaryotic vs. eukaryotic), cellular organization (unicellular vs. multicellular), mode of nutrition (autotrophic vs. heterotrophic), and reproductive methods. For example, organisms in the plant kingdom are primarily autotrophic and multicellular, while those in the animal kingdom are typically multicellular and heterotrophic. Additionally, genetic and evolutionary relationships are considered to classify organisms within these kingdoms.

* Kingdom Animalia, Phylum prokaryotae. i disagree, its kingdon prokaryote
Separating organisms into unicellular and multicellular categories might not be useful because some unicellular organisms may be more closely related to multicellular organisms than to other unicellular ones. Additionally, this classification overlooks important differences within each group, such as varying levels of complexity or ancestral relationships. Therefore, grouping solely based on cell number could oversimplify the diversity and evolutionary history of organisms.
They are unicellular organisms with no defined nucleas.
the five kingdom classification system asks whether a cell is pro or eukaryotic, whether it is auto or heterotrophic, by structure and function, if it is produced in an embryo, and if it is unicellular or. multicellular
Organisms can be classified based on their cell structure, with unicellular organisms consisting of a single cell that carries out all life processes independently, while multicellular organisms are made up of multiple specialized cells that work together to perform specific functions. This classification helps distinguish between simple, single-celled life forms and more complex, multi-celled organisms.
lichens, corals, viruses, corals, viruses and carnivourous plants are difficult to classify :)
