To their surprise they discovered unicellular(one cell) organisms in the samples. These organisms are todayclassified in the kingdom, Archaebacteria.Archaebacteria are found in extreme environments such as hotboiling water and thermal vents under conditions with no oxygen orhighly acid environments. Just so, are archaebacteria Heterotrophs?
Originally Answered: Is archaebacteria cosideredheterotrophic or autotrophic? Archaebacteria areclassified as autotrophs. They make their food from the basicmaterials in their environment like carbon, oxygen, hydrogen,metals and simple organic molecules such as sugar.
Secondly, are archaebacteria asexual or sexually? Only prokaryotes (the archaea and the bacteria)reproduce asexually through binary fission. Eukaryotes (suchas protists and unicellular fungi) may reproduce in a functionallysimilar manner by mitosis; most of these are also capable ofsexual reproduction. Many Asexual cells normally dieoff.
Hereof, are eubacteria unicellular?
The Eubacteria are all easily stained, rod-shapedor spherical bacteria. They are generally unicellular, but asmall number of multicellular forms do occur.
What kind of cells do archaebacteria have?
Archaebacteria. Archaebacteria aresingle-celled prokaryotes originally thought to be bacteria. Theyare in the Archaea Domain and have a unique ribosomal RNAtype. The cell wall composition of these extremeorganisms allows them to live in some very inhospitable places,such as hot springs and hydrothermal vents.

Are Archaea Autotroph?
Archaea can be both autotrophic andheterotrophic. Archaea are very metabolically diverse. Somespecies of archaea are autotrophic. Do archaebacteria have a nucleus?
Archaebacteria, like all prokaryotes, haveno membrane bound organelles. This means that thearchaebacteria are without nuclei, mitochondria,endoplasmic reticula, lysosomes, Golgi complexes, or chloroplasts.Because these organisms have no nucleus, the geneticmaterial floats freely in the cytoplasm. How do archaebacteria reproduce?
Reproduction. Archaea reproduce asexuallyby binary or multiple fission, fragmentation, or budding; mitosisand meiosis do not occur, so if a species of archaea existsin more than one form, all have the same genetic material. Bothbacteria and eukaryotes, but not archaea, make spores. Are archaebacteria eukaryotic?
In subsequent years, molecular phylogenetic analysesindicated that eukaryotes and the Archaea representsister groups in the tree of life. During the genomic era, itbecame evident that eukaryotic cells possess a mixture ofarchaeal and bacterial features in addition toeukaryotic-specific features. Can archaea move?
Structural diversity among archaeans is notlimited to the overall shape of the cell. Archaea may haveone or more flagella attached to them, or may lack flagellaaltogether. The flagella are hair-like appendages used formoving around, and are attached directly into the outermembrane of the cell. Are animals eukaryotic?
Eukaryotes are organisms made up of cells thatpossess a membrane-bound nucleus (that holds DNA in the form ofchromosomes) as well as membrane-bound organelles.Eukaryotic organisms may be multicellular or single-celledorganisms. All animals are eukaryotes. Othereukaryotes include plants, fungi, and protists. Does Animalia have a nucleus?
Animalia. Animals are multicellular, and movewith the aid of cilia, flagella, or muscular organs based oncontractile proteins. They have organelles including anucleus, but no chloroplasts or cell walls. Animals acquirenutrients by ingestion. What are characteristics of archaebacteria?
Archaebacteria have lipids in their cellmembranes. They are composed of branched hydrocarbon chains,connected to glycerol by ether linkages. Since these organismsdon't have nuclei, the genetic material floats freely in thecytoplasm. They consist of ribosomal RNA (rRNA). How do eubacteria reproduce?
Eubacteria reproduce through a relatively simpleprocess known as binary fission, meaning "division in half." MostDNA can be contained on a single chromosome, which can reach greatlengths if stretched out, and the bacteria duplicate theinformation and split into two. Archaebacteria use the sameprocess. Do eubacteria have a nucleus?
Like archeans, eubacteria are prokaryotes,meaning their cells do not have nuclei in which theirDNA is stored. This distinguishes both groups from the eukaryotes,whose DNA is contained in a nucleus. Eubacteria areenclosed by a cell wall. Are there 5 or 6 kingdoms?
There are 6 kingdoms in taxonomy. Everyliving thing comes under one of these 6 kingdoms. The sixkingdoms are Eubacteria, Archae, Protista, Fungi, Plantae,and Animalia. Until the 20th century, most biologists consideredall living things to be classifiable as either a plant or ananimal. Can eubacteria move?
Eubacteria can move freely and an be foundeverywhere. So they are often Pathogenic, meaning the canmove freely. some have a flagellum (flagella singular) it is along whip-like structure attached to them allowing them tomove. The bacteria whips its flagella around to help itmove in the correct direction. How many cells do eubacteria have?

During multiplication, this single cell dividesto produce two progeny cells in a process called transversebinary fission. What is eubacteria in biology?
Definition. noun, singular: eubacterium.Literally means true bacteria, which includes all bacteria exceptfor archaebacteria. Supplement. These bacteria form the domainBacteria, previously called domain Eubacteria. How can eubacteria be helpful?
Eubacteria do not have nucleus and cellorganelles. Eubacteria in the human guts play important rolein digestion of food and synthesis of vitamin K. They also protecthuman body from harmful bacteria. Some Eubacteria can induceserious diseases such as tuberculosis, meningitis, anthrax,leprosy, cholera and tetanus. Are eubacteria prokaryotic or eukaryotic?
While both archaebacteria and eubacteria areprokaryotic, they are evolutionarily different. Allprokaryotic cells are unicellular, have a cell wall and lackboth a nucleus and membrane-bound organelles. The domain bacteriacontains the kingdom eubacteria and is known as truebacteria.

Archaea (formerly Archaebacteria) are alive. Sothey do have DNA, but like the bacteria, their DNA isnot in a nucleus. The DNA is not surrounded with a membranelike it is in the cells of plants, animals, fungi, algae, andprotozoa. All living things either have cells or arecells. Is Plantae asexual?
Plantae. Plants can also reproduce sexually andasexually. Plants can asexually reproduce viabudding, fragmentation, rhizomes or stolons. Rhizomes are the mainstems of a plant which can be cut into piece and can give rise to anew plant (e.g ginger). What is a characteristic of archaea?
1. Cell walls: virtually all bacteria containpeptidoglycan in their cell walls; however, archaea andeukaryotes lack peptidoglycan. Various types of cell walls exist inthe archaea. Therefore, the absence or presence ofpeptidoglycan is a distinguishing feature between thearchaea and bacteria. What are the 7 kingdoms of classification?

Does bacteria have a nucleus?
Bacteria are considered to be prokaryotes, whichmeans they do not have a nucleus and othermembrane-bound organelles. Instead, the DNA is found in thenuceloid, a region with no membrane, or as a plasmid, a smallcircle of extra genetic information, floating right in thecytoplasm, the fluid that fills the cell. Do archaebacteria make their own food?
Most archaea do not make their own food.Many absorb their food sources, in a similar way tobacteria. Archaeans that do make their own food do notmake it through photosynthesis — that is, using carbondioxide, water, and the sun's energy. What kingdoms are in archaea?
