Question

how is prokaryotic cell different from eukaryotic cell? answer briefly

Answer 1

Similarities —
Eukaryotic Cell versus Prokaryotic Cell comparison chart
Eukaryotic Cell Prokaryotic Cell
Nucleus Present Absent
Number of chromosomes More than one One--but not true chromosome: Plasmids
Cell Type Usually multicellular Usually unicellular (some cyanobacteria may be multicellular)
True Membrane bound Nucleus Present Absent
Example Animals and Plants Bacteria and Archaea
Genetic Recombination Meiosis and fusion of gametes Partial, undirectional transfers DNA
Lysosomes and peroxisomes Present Absent
Microtubules Present Absent or rare
Endoplasmic reticulum Present Absent
Mitochondria Present Absent
Cytoskeleton Present May be absent
DNA wrapping on proteins. Eukaryotes wrap their DNA around proteins called histones. Multiple proteins act together to fold and condense prokaryotic DNA. Folded DNA is then organized into a variety of conformations that are supercoiled and wound around tetramers of the HU protein.
Ribosomes larger smaller
Vesicles Present Present
Golgi apparatus Present Absent
Chloroplasts Present (in plants) Absent; chlorophyll scattered in the cytoplasm
Flagella Microscopic in size; membrane bound; usually arranged as nine doublets surrounding two singlets Submicroscopic in size, composed of only one fiber
Permeability of Nuclear Membrane Selective not present
Plasma membrane with steroid Yes Usually no
Cell wall Only in plant cells and fungi (chemically simpler) Usually chemically complexed
Vacuoles Present Present
Cell size 10-100um 1-10um
