Eukaryote

table below, compare prokaryote and eukaryote cells. Prokaryote Eukaryote 70S (small) ribosomes The nucleoid is naked DNA No mitochondria Cell parts The cell parts float in the cytoplasm Under 10 micrometers in diameter 80S (large) ribosomes True nucleus contains DNA Mitocondria Organelles in discrete membranes Internal membranes enclose organelles 10-15µm in diameter 2. What is the literal meaning of the term eukaryote? The term ‘eukaryote’ means “true nucleus” because it has...

Origin of Eukaryotes Bio 108

Origin of Eukaryotes * The origin of eukaryotes is important to understand the origin of modern complex cells. There are three main separate theories that hypothesize the origins: the three-domain system, eocyte theory, and endosymbiosis. Each one have there own merits and evidence supporting. These theories suggest the evolution of cells from the most primitive prokaryotes, unicellular organism having cells lacking membrane-bound nuclei, to the most complex eukaryotes, single or multicellular...

Organelles of Prokaryote and Eukaryote Cells

Prokaryote Organelles: Nucleoid Region: The region in a prokaryotic cell consisting of a concentrated mass of DNA. (The “nucleus” of a prokaryotic cell) The nucleoid instructs all the organelles on what to do. Ribosome: A cell organelle consisting of RNA and protein organized into two subunits and functioning as the site of protein synthesis in the cytoplasm. The ribosomal subunits are constructed in the nucleolus. (Make proteins from amino acids) The nucleoid controls the ribsomes and specifies...

Eukaryotics Cells

Eukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus. This feature gives them their name, (also spelled "eucaryote,") which comes from the Greek word referring to the nucleus. Animals, plants, fungi, and protists are eukaryotes. Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the...

DETAILED DIFFERENCES BETWEEN EUKARYOTIC AND PROKARYOTIC CELLS

Cells are divided into two categories namely the Prokaryotes and Eukaryotes. These two have varying differences between them. Speaking in simple cell biology words, prokaryotes are primitive, simple organisms that lack membranous cell organelles. The opposite of this are eukaryotes, which are advanced and complex organisms having membrane bound cell organelles. Seemingly simple in structure and markedly different from eukaryote and protist organisms, prokaryotic cells are believed to have been...

Basic Cellular Functions and Biology

prokaryote- smaller and simpler than eukaryotes, do not contain nuclei, are part of the Bacteria domain, are unicellular, are autotrophs or heterotrophs eukaryote- cells with nuclei and contain specialized structures called organells. All plants, animals and fungi are eukaryotes. Part of the Eukarya domain, Protista, Fungi, Plantae, and Animalia kingdom. plant- eukaryote, cell walls of cellulose, contain chloroplasts, multicellular, autotrophs animal- eukaryote, no cell walls or chloroplasts, multicellular...

Eukaryotic & Prokaryotic Cells

which can be distinguished on the basis of their structure and the complexity of their organization. The simplest organisms which consist of one cell are called prokaryotes. More complex organisms are called eukaryotes and they consist of many cells. Objectives: * Define the terms: Eukaryotes & Prokaryotes with examples * Explain the differences between Eukaryotic cells and Prokaryotic cells with particular reference to the characteristics of their: (Nucleus/nucleoid, DNA, Mitotic division...

History of Microorganisms' Discovery

bacteria and archaea were not recognised and archaea were classified with bacteria as part of the kingdom Monera. However, in 1990 the microbiologist Carl Woese proposed the three-domain system that divided living things into bacteria, archaea and eukaryotes.[28] Archaea differ from bacteria in both their genetics and biochemistry. For example, while bacterial cell membranes are made from phosphoglycerides with ester bonds, archaean membranes are made of ether lipids.[29] Archaea were originally...
