Kingdom Monera Monera are considered as the most primitive group of organisms. They include various types of bacteria and blue-green algae. Monerans are most abundant of all organisms, due to their versa ti lity of their habitat. It is estimated that a single drop of water contai ns 50 billion bacteria. They are primitive organisms. 2  All organisms of the kingdom are prokaryotes. 3  They are present in both living and non-living environment. 4  They can survive in harsh and extreme climatic conditions like in hot springs, acidic soils etc.

- The fungus-like protists are the slime molds and water molds. They are mostly single-celled organisms that live in the moist soil of forest floors and compost piles. These heterotrophs absorb nutrients from decaying organic matter and move in the same fashion as amoebas by extending and pulling with pseudopodia.ingdom Protista contains the protists, or all the organisms that do not fit into the other kingdoms of life. Protists can be heterotrophic or autotrophic, mobile or immobile, single-celled or multi-celled, solo or a member of a colony.

Primitive (phylogenetics) The term primitive (or advanced/derived) is not properly used in reference to an organism or species as every species is a mosaic of primitive and derived traits. Humans, for example have large brains (a derived trait) and five fingers (a primitive trait) in our lineage.he term in biology contains no judgment involving the sophistication, superiority, value or adaptiveness of a trait. Primitive in biology means only that the trait appeared first in the ancestors and has been passed on largely intact to more recent members of the group.

Protozoa The word protozoa (singular protozoon, or protozoan) was coined in 1818, by zoologist Georg August Goldfuss, as the Greek equivalent of the German Urthiere, meaning primitive, or original animals. Goldfuss erected Protozoa as a class containing what he believed to be the simplest animals.Originally, the group included not only microbes, but also some lower multicellular animals, such as rotifers, corals, sponges, jellyfish, bryozoa and polychaete worms.oldfuss erected Protozoa as a class containing what he believed to be the simplest animals.

Monerans are single-celled organisms that have no nucleus or. organelles, they are prokaryotic which means they contain a cell membrane, cell wall, DNA, plasmids (circular pieces of dna), ribosomes and cytoplasm containing enzymmes.ubacteria the largest phyllum are prokaryotic organisms as characterized by the lack of a membrane and enclosed nucleuse. They are unnicellular with DNA in single circular chromosomes, and have a cell wall present.

Primates: Definition, Evolution & Characteristics The most primitive living primates are called prosimians. They are primitive in the sense that they retain characteristics of the very first primates from millions of years ago. Prosimians include lemurs, lorises, galagos and tarsiers.Within simians, the next most primitive group is the new world monkeys.These monkeys are native to North and South America.hey are primitive in the sense that they retain characteristics of the very first primates from millions of years ago.

Protist A protist is any eukaryotic organism that is not an animal, plant or fungus. The protists do not form a natural group, or clade, but are often grouped together for convenience, like algae or invertebrates. In some systems of biological classification, such as the popular five-kingdom scheme proposed by Robert Whittaker in 1969, the protists make up a kingdom called Protista, composed of organisms which are unicellular or unicellular-colonial and which form no tissues. Besides their relatively

- The animal-like protists are also known as protozoans, which is Latin for 'first animals.' All protozoans are single-celled heterotrophs and are categorized based on their movement. Paramecia are examples of protozoans that use cilia, or tiny hairs, to propel themselves through the water.he fungus-like protists are the slime molds and water molds. They are mostly single-celled organisms that live in the moist soil of forest floors and compost piles. These heterotrophs absorb nutrients from decaying organic matter and move in the same fashion as amoebas by extending and pulling with pseudopodia.

Protists are unicellular, some are colonial or multicellular, they do not have specialized tissue organization.The simple cellular organization distinguishes the protists from other eukaryotes.The cell body of the protists contain have a nucleus which is well defined and membrane bound organelles.ingdom Protista are categorized into two taxons: Protozoans-animal-like single-celled organisms. Algae-plant-like single or multi-celled organisms. Animal-like Protists-PROTOZOANS. Protists that have resemblance to animals are known as protozoans.

Characteristics of Monera Bacteria are part of the Moneran kingdom. All members of the kingdom Monera have no nuclei in their cells. All genetic material in these cell floats around in the cytoplasm. They have plasmid DNA. Monerans reproduce both sexually and asexually. digest their food outside of the cell and then absorb the nutrients.

What are some examples of organisms that are prokaryotes and eukaryotes? Most of the prokaryotes are bacteria, such as the Cyanobacteria. Prokaryotes are single-celled and lack a nucleus, but instead they have a nucleoid that contains their DNA. They are the most primitive life form on Earth. Eukaryotes are the organisms that are made up of eukaryotic cells. There is a vast diversity of eukaryotic organisms on Earth. For instance, all the Plants, Fungi and Animals are eukaryotic.

Kingdom (biology) Woese divided the prokaryotes (previously classified as the Kingdom Monera) into two groups, called Eubacteria and Archaebacteria, stressing that there was as much genetic difference between these two groups as between either of them and all eukaryotes.
