PROKARYOTIC VS EUKARYOTIC Flashcards
Mostly small (1–10 μm)
Prokaryotic Cell , Cell size
DNA with some DNA-binding protein; simple, circular
DNA molecule in nucleoid; nucleoid is not membrane bound
Prokaryotic Cell , Genetic system
Direct by binary fission or budding; no mitosis
Prokaryotic Cell , Cell division
Absent in most; highly modified if present
Prokaryotic Cell , Sexual system
Absorption by most; photosynthesis by some
Prokaryotic Cell , Nutrition
No mitochondria; oxidative enzymes bound to cell membrane, not packaged separately; great variation in metabolic pattern
Prokaryotic Cell , Energy metabolism
None Intracellular movement
Prokaryotic Cell
Flagella/cilia , If present, not with “9 + 2” microtubular pattern
Prokaryotic Cell
Contains disaccharide chains cross-linked with peptides in Bacteria, but not in Archaea.
Archeons have ester-linked membrane lipids.
Prokaryotic Cell , Cell wall
Mostly large (10–100 μm)
Eukaryotic Cell , Cell size
DNA complexed with DNA-binding proteins in complex linear
chromosomes within nucleus with membranous envelope; circular
mitochondrial and chloroplast DNA
Eukaryotic Cell , Genetic system
Some form of mitosis; centrioles in many; mitotic spindle present
Eukaryotic Cell , Cell division
Present in most; male and female partners; gametes that fuse to form
zygote
Eukaryotic Cell , Sexual system
Absorption, ingestion; photosynthesis by some
Eukaryotic Cell , Nutrition
Mitochondria present; oxidative enzymes packaged therein; more
unified pattern of oxidative metabolism
Eukaryotic Cell , Energy metabolism
