BIO - PROKARYOTES AND EUKARYOTES

prokaryotic

organisms are metabolically diverse because they can utilize different nutrients and energy sources and they can inhabit all types of environment on earth

prokaryotic

this can be compared to a studio-type of a condominium unit because of the lack of compartments

eukaryotic

this is comparable to a mansion which has several rooms or compartments

eukaryotes

cell wall is either made up or cellulose as in plants and chitin in fungi

prokaryotes

cell wall is made up of peptidoglycan

eukaryotes

sterols are present like cholesterol, phytosterol, and ergosterol

prokaryotes

they do not have sterols in the cell membrane but have a sterol-like lipid component called hopanoid

eukaryotes

endomembrane system is present

eukaryotes

ribosomes can be found in the cytoplasm, outer nuclear membrane, rough endoplasmic reticulum, mitochondrion, and chloroplast

prokaryotes

all ribosomes are found in the cytoplasm

eukaryotes

more than one linear DNA with histone

prokaryotes

one covalent, closed, circular DNA

eukaryotes

have more than one chromosome

prokaryotes

have only one chromosome and an extrachromosomal DNA called a plasmid

eukaryotes

individual cells reproduce through mitosis and meiosis

prokaryores

cells reproduce through binary fission and some reproduce through spores

eukaryotes

have multiple points of origin and use unidirectional replication within the nucleus

prokaryotes

DNA replication occurs in two opposing directions at the time in the cytoplasm

eukaryotes

telomerase is involved in the replication of telomeres of the eukaryotic chromosome

prokaryotes

do not have telomeres so telomerase is not present

eukaryotes

transcription occurs in the nucleus and the translation occurs in the cytoplasm

prokaryotes

transcription and translation can be done at the same time in the cytoplasm
