diffrencetiate between prokaryotic and eukaryotic
Answers
Answer:
BASIS FOR COMPARISON PROKARYOTIC CELLS EUKARYOTIC CELLS
Size 0.5-3um 2-100um
Kind of Cell Single-cell Multicellular
Cell Wall Cell wall present, comprise of peptidoglycan or mucopeptide (polysaccharide). Usually cell wall absent, if present (plant cells and fungus), comprises of cellulose (polysaccharide).
Presence of Nucleus Well-defined nucleus is absent, rather 'nucleoid' is present which is an open region containing DNA. A well-defined nucleus is present enclosed within nuclear memebrane.
Shape of DNA Circular, double-stranded DNA. Linear, double-stranded DNA.
Mitochondria Absent Present
Ribosome 70S 80S
Golgi Apparatus Absent Present
Endoplasmic Reticulum Absent Present
Mode of Reproduction Asexual Most commonly sexual
Cell Divison Binary Fission,
(conjugation, transformation, transduction) Mitosis
Lysosomes and Peroxisomes Absent Present
Chloroplast (Absent) scattered in the cytoplasm. Present in plants, algae.
prokaryotic cell
- poorly defined nuclear region
- size is generally small
- single chromosome is present
- membrane bound cell organelles absent
Eukaryotic cells
- well defined nuclear region
- size is generally large
- more than one chromosome
- membrane bound cell organelles present
