What Makes The Domain Eukarya Unique

The domain eukaryota makes up one of the domains of life in the three domain system.

What makes the domain eukarya unique. Members of the domain eukarya called eukaryotes have more complex cells than prokaryotes. Domain eukaryota is taxonomically devided into seven kingdoms. Eukaryotic cells are typically much larger than those of prokaryotes. Eukaryota consists of organisms that have a true nucleus and structures called organelles that are surrounded by membranes.

The presence of nucleus which contains genetic material and is enclosed by a nuclear membrane sets them apart from prokaryotic cells. It involves separating the duplicated chromosomes through movements directed by microtubules. The kingdoms in the domain eukarya are protista fungi plantae and animalia. Life on earth is genuinely very diverse hence to easily distinguish living organisms early scientists classified them into two kingdoms.

All complex organisms are eukaryotic and they reproduce by mitosis or meiosis. Eukaryotes j uː ˈ k ær i oʊ t s ə t s are organisms whose cells have a nucleus enclosed within a nuclear envelope. Like bacteria archaea are prokaryotic organisms and do not have a membrane bound nucleus. Eukaryotes belong to the domain eukaryota or eukarya.

Because they are very similar to bacteria in appearance they were originally mistaken for bacteria. These are organisms with cells that contain a nucleus as well as membrane bound organelles. Cell division in eukaryotes is different from prokaryotes that lack a nucleus. Their name comes from the greek εὖ eu well or good and κάρυον karyon nut or kernel.

The eukarya ribosomal rna rrna sequence is unique and different from either the archea or the bacteria 4. The three domains are the archaea the bacteria and the eukarya. There are two types of division processes. They contain membrane abound organelles of various types including a nucleus where genetic information.

The kingdoms most associated with eukarya are the plantae. However during the 19th century this classification was challenged by numerous pieces of evidence that were just too insufficient to explain such diversity. This archaea domain contains single celled organisms. Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell s ribosomal rnas rrna the cell s membrane lipid structure and its sensitivity to antibiotics.

Archaea have genes that are similar to both bacteria and eukaryotes. Eukarya includes eukaryotic organisms.
