write different between prokaryotic cell and ekiryotics cell
Answers
Eukaryotic Cell Prokaryotic Cell
1)Nucleus
Present Absent
2)Number of chromosomes
More than one One--but not true
chromosome: Plasmids
3)Cell Type
Usually multicellular Usually unicellular
(some
cyanobacteria may
be multicellular)
4)True Membrane bound Nucleus
Present Absent
5)Example
Animals and Plants Bacteria and
archaea
6)Genetic Recombination
Meiosis and fusion
of gametes Partial,
undirectional
transfers DNA
7)Lysosomes and peroxisomes
Present Absent
8)Microtubules
Present Absent or
rare
9)Endoplasmic reticulum
Present Absent
10)Mitochondria
Present Absent
11)Cytoskeleton
Present Absent
12)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.
13)Ribosomes
larger smaller
14)Vesicles
Present Present
15)Cell size
10-100um 1-10um
16)Flagella
Microscopic in size;
membrane bound;
usually arranged as
nine doublets surrounding
two singlets
Submicroscopic in
size, composed of
only one fiber
