What is the meaning of Karyotic? An organism whose cells contain a nucleus surrounded by a membrane and whose DNA is bound together by proteins (histones) into chromosomes. The cells of eukaryotes also contain an endoplasmic reticulum and numerous specialized organelles not present in prokaryotes, especially mitochondria, Golgi bodies, and lysosomes.

What is the true meaning of prokaryote?
Definition of prokaryote : any of the typically unicellular microorganisms that lack a distinct nucleus and membrane-bound organelles and that are classified as a kingdom (Prokaryotae synonym Monera) or into two domains (Bacteria and Archaea) — compare archaea, bacterium, eukaryote.
What is Karyotic and eukaryotic?
Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
What is the meaning of EU and Karyotic?
Etymology: the term eukaryote (plural: eukaryotes) came from Greek 'eu', meaning “good”, “well”, “true” and ”káry(on)”, meaning “nut”, “kernel”. The term eukaryotic is a derived word and used to refer to eukaryote. Compare: prokaryote.
Why bacteria are called prokaryotes?
Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.
What are 3 examples of prokaryotic cells?
Examples of prokaryotes are bacteria, archaea, and cyanobacteria (blue-green algae).
What is called eukaryotic cell?
Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular.

What are called prokaryotic cell?
Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.
Does EU stand for Europe?
The European Union1 The European Union in brief. The European Union (EU) is a unique economic and political union between 27 European countries. The predecessor of the EU was created in the aftermath of the Second World War.
What is EU from eukaryotic mean?
wellThe word eukaryote comes from the Greek eu, "well," and karyon, "nut or kernel," which is a common scientific word-forming element that's used to talk about the nuclei of cells.
Why is it called eukaryote?
Eukaryotes (/juːˈkærioʊts, -əts/) are organisms whose cells have a nucleus enclosed within a nuclear envelope. They belong to the group of organisms Eukaryota or Eukarya; their name comes from the Greek εὖ (eu, "well" or "good") and κάρυον (karyon, "nut" or "kernel").
What is the definition of a cell?
biology. (of a cell) containing a nucleus and other structures, each with its own purpose. (Definition of eukaryotic from the Cambridge Academic Content Dictionary © Cambridge University Press)
What are eukaryotic genes made of?
Eukaryotic genes are composed of exons and introns. From the Cambridge English Corpus. But it is impossible to explain how prokaryotes cells evolved into eukaryotic cells (without creating intermediary organisms out of thin air). From the Cambridge English Corpus.
Do eukaryotic cells have a plasma membrane?
Eukaryotic cells contain a plasma membrane and distinct membrane-bound organelles. From the Cambridge English Corpus. The role of stable complexes that repress and activate eukaryotic genes. From the Cambridge English Corpus. Moreover, it has been reported that eukaryotic cells secrete chaperonins.
Do eukaryotic genomes have the highest affinity?
eukaryotic. Evidently, even the highest-affinity sequences in natural eukaryotic genomes are not evolved for highest possible affinity. From the Cambridge English Corpus. One can envision early eukaryotic organisms as being under pressure to incorporate more and more genes as they fine-tuned their eukaryotic machinery.
